ITextTemplatingEngineHost.ResolveAssemblyReference 方法

2011-08-12

允许主机提供有关程序集位置的附加信息。

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 ResolveAssemblyReference ( _
    assemblyReference As String _
) As String

string ResolveAssemblyReference(
    string assemblyReference
)

String^ ResolveAssemblyReference(
    String^ assemblyReference
)

abstract ResolveAssemblyReference : 
        assemblyReference:string -> string

function ResolveAssemblyReference(
    assemblyReference : String
) : String

参数

assemblyReference
类型：System.String
要解析的程序集。

返回值

类型：System.String
一个 String，其中包含指定的程序集引用或指定的程序集引用以及附加信息。

备注

如果用户在文本模板中指定可选的 assembly 指令，该引擎将调用此方法。对于每个文本模板转换，可以调用此方法 0 次、1 次或多次。有关更多信息，请参见 T4 文本模板指令。

主机可以在不同位置按它想要的顺序搜索程序集，或者添加程序集引用开始的选择路径。

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 string ResolveAssemblyReference(string assemblyReference)
{
    //if the argument is the fully qualified path of an existing file,
    //then we are done (this does not do any work)
    //----------------------------------------------------------------
    if (File.Exists(assemblyReference))
    {
        return assemblyReference;
    }

    //the assembly might be in the same folder as the text template that 
    //called the directive
    //----------------------------------------------------------------
    string candidate = Path.Combine(Path.GetDirectoryName(this.inputFile), assemblyReference);
    if (File.Exists(candidate))
    {
        return candidate;
    }
        
    //this can be customized to search specific paths for the file,
    //or to search the GAC
    //----------------------------------------------------------------

    //this can be customized to accept paths to search as command line
    //arguments
    //----------------------------------------------------------------

    //if we cannot do better - return the original file name
    return "";
}
