Public Function GetArrayMethodToken (arrayClass As Type, methodName As String, callingConvention As CallingConventions, returnType As Type, parameterTypes As Type()) As MethodToken

參數

arrayClass
Type

陣列的物件。

methodName
String

一個包含方法名稱的字串。

callingConvention
CallingConventions

方法的呼叫慣例。

returnType

傳回

MethodToken

在陣列類別上命名方法的標記。

例外狀況

ArgumentException

arrayClass 不是陣列。

-或-

的 methodName 長度為零。

ArgumentNullException

arrayClass 或 methodName 為 null。

範例

以下範例示範如何使用 來 GetArrayMethod 取得對應的 ， MethodToken 該方法會回傳陣列值。

// Define a dynamic module in "TempAssembly" assembly.
ModuleBuilder myModuleBuilder = myAssemblyBuilder.
                              DefineDynamicModule("TempModule");
// Define a runtime class with specified name and attributes.
TypeBuilder myTypeBuilder = myModuleBuilder.DefineType
                           ("TempClass",TypeAttributes.Public);
Type[] paramArray = {typeof(Array)};
// Add 'SortArray' method to the class, with the given signature.
MethodBuilder myMethod = myTypeBuilder.DefineMethod("SortArray",
                          MethodAttributes.Public,typeof(Array),paramArray);

Type[] myArrayClass = new Type[1];
Type[] parameterTypes = {typeof(Array)};
// Get the 'MethodInfo' object corresponding to 'Sort' method of 'Array' class.
MethodInfo myMethodInfo=myModuleBuilder.GetArrayMethod(
            myArrayClass.GetType(),"Sort",CallingConventions.Standard,
                                                                         null,parameterTypes);
// Get the token corresponding to 'Sort' method of 'Array' class.
MethodToken myMethodToken=myModuleBuilder.GetArrayMethodToken(
            myArrayClass.GetType(),"Sort",CallingConventions.Standard,
                                                                        null,parameterTypes);
Console.WriteLine("Token used by module to identify the 'Sort' method"
                            + " of 'Array' class is : {0:x} ",myMethodToken.Token);

ILGenerator methodIL = myMethod.GetILGenerator();
methodIL.Emit(OpCodes.Ldarg_1);
methodIL.Emit(OpCodes.Call,myMethodInfo);
methodIL.Emit(OpCodes.Ldarg_1);
methodIL.Emit(OpCodes.Ret);

// Complete the creation of type.
myTypeBuilder.CreateType();

' Define a dynamic module in "TempAssembly" assembly.
Dim myModuleBuilder As ModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule")
' Define a runtime class with specified name and attributes.
Dim myTypeBuilder As TypeBuilder = _
            myModuleBuilder.DefineType("TempClass", TypeAttributes.Public)
Dim myParamArray() As Type = New Type() {GetType(Array)}
' Add 'SortArray' method to the class, with the given signature.
Dim myMethod As MethodBuilder = _
   myTypeBuilder.DefineMethod("SortArray", MethodAttributes.Public, _
   GetType(Array), myParamArray)

Dim myArrayClass(0) As Type
Dim parameterTypes() As Type = New Type() {GetType(Array)}
' Get the 'MethodInfo' object corresponding to 'Sort' method of 'Array' class.
Dim myMethodInfo As MethodInfo = _
   myModuleBuilder.GetArrayMethod(myArrayClass.GetType(), "Sort", _
   CallingConventions.Standard, Nothing, parameterTypes)
' Get the token corresponding to 'Sort' method of 'Array' class.
Dim myMethodToken As MethodToken = _
      myModuleBuilder.GetArrayMethodToken(myArrayClass.GetType(), _
      "Sort", CallingConventions.Standard, Nothing, parameterTypes)
Console.WriteLine("Token used by module to identify the 'Sort' method" + _
                  " of 'Array' class is : {0:x} ", myMethodToken.Token)
Dim methodIL As ILGenerator = myMethod.GetILGenerator()
methodIL.Emit(OpCodes.Ldarg_1)
methodIL.Emit(OpCodes.Call, myMethodInfo)
methodIL.Emit(OpCodes.Ldarg_1)
methodIL.Emit(OpCodes.Ret)
' Complete the creation of type.
myTypeBuilder.CreateType()

備註

此方法與 GetArrayMethod類似，不同之處在於回傳陣列方法的標記，而非方法本身。
