示例

下面的示例演示如何使用 GetArrayMethod 来获取 MethodInfo 对应于返回数组值的方法的。The following example demonstrates how to use GetArrayMethod to obtain the MethodInfo corresponding to a method that returns an array value.

// 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 );
array<Type^>^ paramArray = { Array::typeid };
// Add 'SortArray' method to the class, with the given signature.
MethodBuilder^ myMethod = myTypeBuilder->DefineMethod( "SortArray",
   MethodAttributes::Public, Array::typeid, paramArray );

array<Type^>^ myArrayClass = gcnew array<Type^>( 1 );
array<Type^>^ parameterTypes = { Array::typeid };
// Get the 'MethodInfo' object corresponding to 'Sort' method of 'Array' class.
MethodInfo^ myMethodInfo = myModuleBuilder->GetArrayMethod(
   myArrayClass->GetType(), "Sort", CallingConventions::Standard,
   nullptr, parameterTypes );

// Get the token corresponding to 'Sort' method of 'Array' class.
MethodToken myMethodToken = myModuleBuilder->GetArrayMethodToken(
   myArrayClass->GetType(), "Sort", CallingConventions::Standard,
   nullptr, 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.
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()

注解

GetArrayMethod 如果有一个类型的数组,该类型的定义尚未完成并且你想要访问上定义的方法,则此方法非常有用 ArrayGetArrayMethod is useful when you have an array of a type whose definition has not been completed and you want to access methods defined on Array. 例如,你可以定义一个类型,并需要定义一个方法,该方法采用类型的数组作为参数。For example, you might define a type and want to define a method that takes an array of the type as a parameter. 若要访问数组的元素,需要调用类的方法 ArrayIn order to access the elements of the array, you will need to call methods of the Array class.
