Definition

Returns the token for the named method on an array class.

public:
 System::Reflection::Emit::MethodToken GetArrayMethodToken(Type ^ arrayClass, System::String ^ methodName, System::Reflection::CallingConventions callingConvention, Type ^ returnType, cli::array <Type ^> ^ parameterTypes);
public System.Reflection.Emit.MethodToken GetArrayMethodToken (Type arrayClass, string methodName, System.Reflection.CallingConventions callingConvention, Type returnType, Type[] parameterTypes);
member this.GetArrayMethodToken : Type * string * System.Reflection.CallingConventions * Type * Type[] -> System.Reflection.Emit.MethodToken
Public Function GetArrayMethodToken (arrayClass As Type, methodName As String, callingConvention As CallingConventions, returnType As Type, parameterTypes As Type()) As MethodToken

Parameters

arrayClass
Type Type Type Type

The object for the array.

methodName
String String String String

A string that contains the name of the method.

callingConvention
CallingConventions CallingConventions CallingConventions CallingConventions

The calling convention for the method.

returnType
Type Type Type Type

The return type of the method.

parameterTypes
Type[]

The types of the parameters of the method.

Returns

The token for the named method on an array class.

Exceptions

arrayClass is not an array.

-or-

The length of methodName is zero.

Examples

The following example demonstrates how to use GetArrayMethod to obtain the MethodToken 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();

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)

Remarks

This method is similar to GetArrayMethod, except that it returns the token of the array method instead of the method itself.
