示例

下面的代码示例演示如何使用 SaveAs 方法。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

注解

方法将Configuration对象中的配置设置保存到基于saveModeforceSaveAll参数的新文件。 SaveAsThe SaveAs method persists configuration settings in the Configuration object to a new file based on the saveMode and forceSaveAll parameters.

如果配置文件不存在于FilePath属性表示的物理位置,则将创建一个新的配置文件,以包含与继承的配置不同的任何设置。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.

如果在创建此Configuration对象后配置文件发生了更改,则会发生运行时错误。If the configuration file has changed since this Configuration object was created, a run-time error occurs.
