MethodBuilder.SetSymCustomAttribute(String, Byte[]) 方法

定义

命名空间:

System.Reflection.Emit

程序集:

mscorlib.dll

使用 blob 设置符号自定义属性。

public:
 void SetSymCustomAttribute(System::String ^ name, cli::array <System::Byte> ^ data);

public void SetSymCustomAttribute (string name, byte[] data);

member this.SetSymCustomAttribute : string * byte[] -> unit

Public Sub SetSymCustomAttribute (name As String, data As Byte())

参数

name

String

符号自定义属性的名称。

data

Byte[]

表示符号自定义属性的值的字节 blob。

例外

InvalidOperationException

该包含类型是以前使用 CreateType() 创建的。

- 或 -

包含此方法的模块不是调试模块。

- 或 -

对于当前的方法，属性 IsGenericMethod 为 true，但属性 IsGenericMethodDefinition 为 false。

示例

下面的代码示例演示了 方法的 SetSymCustomAttribute 上下文用法，用于设置附加到方法的自定义属性的名称和键的字节值。

array<Type^>^ temp0 = { String::typeid };
MethodBuilder^ myMethod = myDynamicType->DefineMethod( "MyMethod",
                          MethodAttributes::Public,
                          int::typeid,
                          temp0 );

// A 128-bit key in hex form, represented as a Byte array.
array<Byte>^ keyVal = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
                        0x00, 0x00, 0x00, 0x00, 0x00, 0x60, 0xFF, 0xFF};

System::Text::ASCIIEncoding^ encoder = gcnew System::Text::ASCIIEncoding;
array<Byte>^ symFullName = encoder->GetBytes( "My Dynamic Method" );

myMethod->SetSymCustomAttribute( "SymID", keyVal );
myMethod->SetSymCustomAttribute( "SymFullName", symFullName );

MethodBuilder myMethod = myDynamicType.DefineMethod("MyMethod",
                    MethodAttributes.Public,
                    typeof(int),
                    new Type[] { typeof(string) });

// A 128-bit key in hex form, represented as a byte array.
byte[] keyVal = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
          0x00, 0x00, 0x00, 0x00, 0x00, 0x60, 0xFF, 0xFF };	

System.Text.ASCIIEncoding encoder = new System.Text.ASCIIEncoding();
byte[] symFullName = encoder.GetBytes("My Dynamic Method");

myMethod.SetSymCustomAttribute("SymID", keyVal);
myMethod.SetSymCustomAttribute("SymFullName", symFullName);

Dim myMethod As MethodBuilder = myDynamicType.DefineMethod("MyMethod", _
               MethodAttributes.Public, GetType(Integer), _
               New Type() {GetType(String)})

' A 128-bit key in hex form, represented as a byte array.
Dim keyVal As Byte() =  {&H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, _
             &H0, &H0, &H0, &H0, &H0, &H60, &HFF, &HFF}

Dim encoder As New System.Text.ASCIIEncoding()
Dim symFullName As Byte() = encoder.GetBytes("My Dynamic Method")

myMethod.SetSymCustomAttribute("SymID", keyVal)
myMethod.SetSymCustomAttribute("SymFullName", symFullName)

注解

与元数据自定义属性不同，此自定义属性与符号编写器相关联。
