提供运行所生成转换类的应用程序域。

命名空间： Microsoft.VisualStudio.TextTemplating
程序集： Microsoft.VisualStudio.TextTemplating.Interfaces.10.0（在 Microsoft.VisualStudio.TextTemplating.Interfaces.10.0.dll 中）

语法

声明
Function ProvideTemplatingAppDomain ( _
    content As String _
) As AppDomain

AppDomain ProvideTemplatingAppDomain(
    string content
)

AppDomain^ ProvideTemplatingAppDomain(
    String^ content
)

abstract ProvideTemplatingAppDomain : 
        content:string -> AppDomain

function ProvideTemplatingAppDomain(
    content : String
) : AppDomain

参数

content
类型：System.String
要处理的文本模板文件的内容。

返回值

类型：System.AppDomain
一个 AppDomain，它将编译和执行所生成的转换类。

备注

主机可以使用 content 参数提供特定的 AppDomain，具体取决于要处理的文本模板文件。例如，如果正在重复处理相同模板文件，主机可以缓存一个 AppDomain。如果宿主不需要该信息，宿主可以忽略 content 参数。

示例

下面的代码示例演示了自定义主机的可能实现。此代码示例摘自一个更大的示例。有关完整的示例，请参见演练：创建自定义文本模板宿主。

public AppDomain ProvideTemplatingAppDomain(string content)
{
    //this host will provide a new application domain each time the 
    //engine processes a text template
    //-------------------------------------------------------------
    return AppDomain.CreateDomain("Generation App Domain");

    //this could be changed to return the current appdomain, but new 
    //assemblies are loaded into this AppDomain on a regular basis
    //if the AppDomain lasts too long, it will grow indefintely 
    //which might be regarded as a leak

    //this could be customized to cache the application domain for 
    //a certain number of text template generations (for example 10)

    //this could be customized based on the contents of the text 
    //template, which are provided as a parameter for that purpose
}
