ModuleBuilder.GetArrayMethodToken Method (Type, String, CallingConventions, Type, Type[])

 

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

Namespace:   System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

public MethodToken GetArrayMethodToken(
	Type arrayClass,
	string methodName,
	CallingConventions callingConvention,
	Type returnType,
	Type[] parameterTypes
)

Parameters

arrayClass
Type: System.Type

The object for the array.

methodName
Type: System.String

A string that contains the name of the method.

callingConvention
Type: System.Reflection.CallingConventions

The calling convention for the method.

returnType
Type: System.Type

The return type of the method.

parameterTypes
Type: System.Type[]

The types of the parameters of the method.

Return Value

Type: System.Reflection.Emit.MethodToken

The token for the named method on an array class.

Exception Condition
ArgumentException

arrayClass is not an array.

-or-

The length of methodName is zero.

ArgumentNullException

arrayClass or methodName is null.

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

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);
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();
