示例

下面的示例演示如何使用 SetData(String, Object) 方法来创建新的值对。The following example demonstrates how to use the SetData(String, Object) method to create a new value pair. 然后，该示例使用 GetData 方法检索该值，并将其显示在控制台中。The example then uses the GetData method to retrieve the value, and displays it to the console.

using namespace System;
using namespace System::Reflection;

int main()
{
   // appdomain setup information
   AppDomain^ currentDomain = AppDomain::CurrentDomain;
   
   //Create a new value pair for the appdomain
   currentDomain->SetData( "ADVALUE", "Example value" );
   
   //get the value specified in the setdata method
   Console::WriteLine( "ADVALUE is: {0}", currentDomain->GetData( "ADVALUE" ) );
   
   //get a system value specified at appdomainsetup
   Console::WriteLine( "System value for loader optimization: {0}", 
      currentDomain->GetData( "LOADER_OPTIMIZATION" ) );
}

/* This code example produces the following output:

ADVALUE is: Example value
System value for loader optimization: NotSpecified
 */

using System;
using System.Reflection;

class ADGetData 
{
    public static void Main() 
    {
        // appdomain setup information
        AppDomain currentDomain = AppDomain.CurrentDomain;

        //Create a new value pair for the appdomain
        currentDomain.SetData("ADVALUE", "Example value");

        //get the value specified in the setdata method
        Console.WriteLine("ADVALUE is: " + currentDomain.GetData("ADVALUE"));

        //get a system value specified at appdomainsetup
        Console.WriteLine("System value for loader optimization: {0}",
            currentDomain.GetData("LOADER_OPTIMIZATION"));
    }
}

/* This code example produces the following output:

ADVALUE is: Example value
System value for loader optimization: NotSpecified
 */

Imports System.Reflection

Class ADGetData   
   
   Public Shared Sub Main()
      ' appdomain setup information
      Dim currentDomain As AppDomain = AppDomain.CurrentDomain
      
      'Create a new value pair for the appdomain
      currentDomain.SetData("ADVALUE", "Example value")
      
      'get the value specified in the setdata method
      Console.WriteLine(("ADVALUE is: " & currentDomain.GetData("ADVALUE")))
      
      'get a system value specified at appdomainsetup
      Console.WriteLine("System value for loader optimization: {0}", _
         currentDomain.GetData("LOADER_OPTIMIZATION"))

   End Sub 
End Class 

' This code example produces the following output:
'
'ADVALUE is: Example value
'System value for loader optimization: NotSpecified

注解

使用此方法插入项，或修改名称数据对的内部缓存中的项的值，这些名称数据对描述 AppDomain的此实例的属性。Use this method to insert an entry, or modify the value of an entry in an internal cache of name-data pairs that describe properties of this instance of AppDomain.

缓存自动包含创建应用程序域时插入的预定义系统条目。The cache automatically contains predefined system entries that are inserted when the application domain is created. 不能用此方法插入或修改系统项。You cannot insert or modify system entries with this method. 尝试修改系统条目的方法调用不起任何作用;方法不会引发异常。A method call that attempts to modify a system entry has no effect; the method does not throw an exception. 您可以用 GetData 方法检查系统项的值，或 GetData中所述的等效 AppDomainSetup 属性。You can inspect the values of system entries with the GetData method, or the equivalent AppDomainSetup properties described in GetData.

您可以调用此方法来设置默认超时间隔的值，以便通过将 "REGEX_DEFAULT_MATCH_TIMEOUT" 作为 name 参数的值并将一个表示超时间隔的 TimeSpan 值作为 data 参数的值来计算正则表达式模式。You can call this method to set the value of the default timeout interval for evaluating regular expression patterns by supply "REGEX_DEFAULT_MATCH_TIMEOUT" as the value of the name argument and a TimeSpan value that represents the timeout interval as the value of the data argument. 还可以通过此方法插入或修改自己的用户定义的名称数据对，并通过 GetData 方法检查其值。You can also insert or modify your own user defined name-data pairs with this method and inspect their values with the GetData method.

使用此方法可在描述应用程序域属性的名称/数据对的内部缓存中插入或修改自己的用户定义条目。Use this method to insert or modify your own user-defined entries in an internal cache of name/data pairs that describe properties of the application domain. 插入项时，可以指定在检索项时要强制执行的权限请求。此外，您可以调用此方法来设置默认超时间隔的值，以便通过提供 "REGEX_DEFAULT_MATCH_TIMEOUT" 作为 name 参数的值，并将一个表示超时间隔的 TimeSpan 值作为 data 参数的值来计算正则表达式模式。When you insert an entry, you can specify a permission demand to enforce when the entry is retrieved.In addition, you can call this method to set the value of the default timeout interval for evaluating regular expression patterns by supply "REGEX_DEFAULT_MATCH_TIMEOUT" as the value of the name argument and a TimeSpan value that represents the timeout interval as the value of the data argument.

不能使用此方法向系统定义的属性字符串分配安全要求。You cannot use this method to assign a security demand to a system-defined property string.

缓存自动包含创建应用程序域时插入的预定义系统条目。The cache automatically contains predefined system entries that are inserted when the application domain is created. 不能用此方法插入或修改系统项。You cannot insert or modify system entries with this method. 尝试修改系统条目的方法调用不起任何作用;方法不会引发异常。A method call that attempts to modify a system entry has no effect; the method does not throw an exception. 可以用 GetData 方法或 GetData 方法的 "备注" 部分中所述的等效 AppDomainSetup 属性检查系统项的值。You can inspect the values of system entries with the GetData method or the equivalent AppDomainSetup properties described in the Remarks section for the GetData method.
