cref 屬性 (C# 程式設計手冊)

XML 文件標籤中的 cref 屬性 (Attribute) 意指「程式碼參考」， 指出標籤的內部文字是程式碼項目，例如型別、方法或屬性 (Property)。 像 Sandcastle (英文) 這樣的文件工具會使用 cref 屬性，自動產生記載型別或成員之頁面的超連結。

範例

下列範例顯示使用於 <see> 標記中的 cref 屬性。

// Save this file as CRefTest.cs 
// Compile with: csc CRefTest.cs /doc:Results.xml  

namespace TestNamespace
{
    /// <summary> 
    /// TestClass contains several cref examples. 
    /// </summary> 
    public class TestClass
    {
        /// <summary> 
        /// This sample shows how to specify the <see cref="TestClass"/> constructor as a cref attribute.�
        /// </summary> 
        public TestClass()
        { }

        /// <summary> 
        /// This sample shows how to specify the <see cref="TestClass(int)"/> constructor as a cref attribute.�
        /// </summary> 
        public TestClass(int value)
        { }

        /// <summary> 
        /// The GetZero method. 
        /// </summary> 
        /// <example>  
        /// This sample shows how to call the <see cref="GetZero"/> method.
        /// <code> 
        /// class TestClass  
        /// { 
        ///     static int Main()  
        ///     { 
        ///         return GetZero(); 
        ///     } 
        /// } 
        /// </code> 
        /// </example> 
        public static int GetZero()
        {
            return 0;
        }

        /// <summary> 
        /// The GetGenericValue method. 
        /// </summary> 
        /// <remarks>  
        /// This sample shows how to specify the <see cref="GetGenericValue"/> method as a cref attribute.
        /// </remarks> 

        public static T GetGenericValue<T>(T para)
        {
            return para;
        }
    }

    /// <summary> 
    /// GenericClass. 
    /// </summary> 
    /// <remarks>  
    /// This example shows how to specify the <see cref="GenericClass{T}"/> type as a cref attribute.
    /// </remarks> 
    class GenericClass<T>
    {
        // Fields and members.
    }

    class Program
    {
        static int Main()
        {
            return TestClass.GetZero();
        }
    }
}

編譯之後，程式會產生下列 XML 檔案。 請注意，舉例來說，編譯器已將 GetZero 方法的cref屬性轉換為 "M:TestNamespace.TestClass.GetZero"。 "M:" 前置詞意指「方法」，而且是文件工具 (例如，Sandcastle) 所能辨識的慣例。 如需前置詞的完整清單，請參閱處理 XML 檔案 (C# 程式設計手冊)。
