SaveAs(String, ConfigurationSaveMode) SaveAs(String, ConfigurationSaveMode) SaveAs(String, ConfigurationSaveMode) SaveAs(String, ConfigurationSaveMode)

Writes the configuration settings contained within this Configuration object to the specified XML configuration file.

SaveAs(String, ConfigurationSaveMode, Boolean) SaveAs(String, ConfigurationSaveMode, Boolean) SaveAs(String, ConfigurationSaveMode, Boolean) SaveAs(String, ConfigurationSaveMode, Boolean)

public:
 void SaveAs(System::String ^ filename);
public void SaveAs (string filename);
member this.SaveAs : string -> unit
Public Sub SaveAs (filename As String)

Parameters

filename
String String String String

The path and file name to save the configuration file to.

Exceptions

The configuration file could not be written to.

-or-

The configuration file has changed.

Remarks

The SaveAs method persists any configuration settings that have been modified since this Configuration object was created to a new file.

If a configuration file does not exist at the physical location represented by the

FilePath property, a new configuration file will be created to contain any settings that are different from the inherited configuration.

If the configuration file has changed since this Configuration object was created, a run-time error occurs.

SaveAs(String, ConfigurationSaveMode) SaveAs(String, ConfigurationSaveMode) SaveAs(String, ConfigurationSaveMode) SaveAs(String, ConfigurationSaveMode)

Writes the configuration settings contained within this Configuration object to the specified XML configuration file.

public:
 void SaveAs(System::String ^ filename, System::Configuration::ConfigurationSaveMode mode);
public void SaveAs (string filename, System.Configuration.ConfigurationSaveMode mode);
member this.SaveAs : string * System.Configuration.ConfigurationSaveMode -> unit
Public Sub SaveAs (filename As String, mode As ConfigurationSaveMode)

Parameters

filename
String String String String

The path and file name to save the configuration file to.

saveMode
ConfigurationSaveMode ConfigurationSaveMode ConfigurationSaveMode ConfigurationSaveMode

A ConfigurationSaveMode value that determines which property values to save.

Exceptions

The configuration file could not be written to.

-or-

The configuration file has changed.

Remarks

The SaveAs method persists configuration settings in the Configuration object to a new file based on the saveMode parameter.

If a configuration file does not exist at the physical location represented by the FilePath property, a new configuration file will be created to contain any settings that are different from the inherited configuration.

If the configuration file has changed since this Configuration object was created, a run-time error occurs.

public:
 void SaveAs(System::String ^ filename, System::Configuration::ConfigurationSaveMode mode, bool forceUpdateAll);
public void SaveAs (string filename, System.Configuration.ConfigurationSaveMode mode, bool forceUpdateAll);
member this.SaveAs : string * System.Configuration.ConfigurationSaveMode * bool -> unit
Public Sub SaveAs (filename As String, mode As ConfigurationSaveMode, forceUpdateAll As Boolean)

Parameters

forceSaveAll
Boolean Boolean Boolean Boolean

true to save even if the configuration was not modified; otherwise, false.

Exceptions

Examples

The following code example demonstrates how to use the SaveAs method.


// Show how to use different modalities to save 
// a configuration file.
static void SaveConfigurationFile()
{
    try
    {

        // Get the current configuration file.
        System.Configuration.Configuration config =
                ConfigurationManager.OpenExeConfiguration(
                ConfigurationUserLevel.None) as Configuration;

        // Save the full configuration file and force save even if the file was not modified.
        config.SaveAs("MyConfigFull.config", ConfigurationSaveMode.Full, true);
        Console.WriteLine("Saved config file as MyConfigFull.config using the mode: {0}",
            ConfigurationSaveMode.Full.ToString());

        config =
                ConfigurationManager.OpenExeConfiguration(
                ConfigurationUserLevel.None) as Configuration;

        // Save only the part of the configuration file that was modified. 
        config.SaveAs("MyConfigModified.config", ConfigurationSaveMode.Modified, true);
        Console.WriteLine("Saved config file as MyConfigModified.config using the mode: {0}",
            ConfigurationSaveMode.Modified.ToString());

        config =
                ConfigurationManager.OpenExeConfiguration(
                ConfigurationUserLevel.None) as Configuration;

        // Save the full configuration file.
        config.SaveAs("MyConfigMinimal.config");
        Console.WriteLine("Saved config file as MyConfigMinimal.config using the mode: {0}",
            ConfigurationSaveMode.Minimal.ToString());

    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine("SaveConfigurationFile: {0}", err.ToString());
    }

}

' Show how to use different modalities to save 
' a configuration file.
Public Shared Sub SaveConfigurationFile()
    Try

        ' Get the current configuration file.
        Dim config As System.Configuration.Configuration = TryCast(ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None), Configuration)

        ' Save the full configuration file and force save even if the file was not modified.
        config.SaveAs("MyConfigFull.config", ConfigurationSaveMode.Full, True)
        Console.WriteLine("Saved config file as MyConfigFull.config using the mode: {0}", ConfigurationSaveMode.Full.ToString())

        config = TryCast(ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None), Configuration)

        ' Save only the part of the configuration file that was modified. 
        config.SaveAs("MyConfigModified.config", ConfigurationSaveMode.Modified, True)
        Console.WriteLine("Saved config file as MyConfigModified.config using the mode: {0}", ConfigurationSaveMode.Modified.ToString())

        config = TryCast(ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None), Configuration)

        ' Save the full configuration file.
        config.SaveAs("MyConfigMinimal.config")
        Console.WriteLine("Saved config file as MyConfigMinimal.config using the mode: {0}", ConfigurationSaveMode.Minimal.ToString())

    Catch err As ConfigurationErrorsException
        Console.WriteLine("SaveConfigurationFile: {0}", err.ToString())
    End Try

End Sub

Remarks

The SaveAs method persists configuration settings in the Configuration object to a new file based on the saveMode and forceSaveAll parameters.

If a configuration file does not exist at the physical location represented by the FilePath property, a new configuration file will be created to contain any settings that are different from the inherited configuration.

If the configuration file has changed since this Configuration object was created, a run-time error occurs.
