備註

如果使用者已經在文字範本中指定了選擇性的 assembly 指示詞，引擎會呼叫這個方法。每個文字範本轉換可呼叫這個方法 0次、1次或多次。如需詳細資訊，請參閱 T4 文字範本指示詞。

主應用程式可以依其慣用的順序來搜尋不同位置中的組件，或將其選擇的路徑加入至組件參考的開頭。

範例

下列程式碼範例示範自訂主機可能的實作。這個程式碼是完整範例的一部分。如需完整的範例，請參閱逐步解說：建立自訂文字範本主機。

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 "";
