ArgumentNullException

arrayClass of methodName is null.

Voorbeelden

In het volgende voorbeeld ziet u hoe GetArrayMethod u de MethodToken bijbehorende methode kunt verkrijgen die een matrixwaarde retourneert.

// 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();

' 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()

Opmerkingen

Deze methode is vergelijkbaar met GetArrayMethod, behalve dat het het token van de matrixmethode retourneert in plaats van de methode zelf.
