ModuleBuilder.GetArrayMethodToken Method

Definition

Namespace:

System.Reflection.Emit

Assembly:

mscorlib.dll

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

C#

public System.Reflection.Emit.MethodToken GetArrayMethodToken(Type arrayClass, string methodName, System.Reflection.CallingConventions callingConvention, Type returnType, Type[] parameterTypes);

Parameters

arrayClass

Type

The object for the array.

methodName

String

A string that contains the name of the method.

callingConvention

CallingConventions

The calling convention for the method.

returnType

Type

The return type of the method.

parameterTypes

Type[]

The types of the parameters of the method.

Returns

MethodToken

The token for the named method on an array class.

Exceptions

ArgumentException

arrayClass is not an array.

-or-

The length of methodName is zero.

ArgumentNullException

arrayClass or methodName is null.

Examples

The following example demonstrates how to use GetArrayMethod to obtain the MethodToken corresponding to a method that returns an array value.

C#

// 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();

Remarks

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