Exceptions

NotSupportedException

This method is not currently supported. Retrieve the method using GetMethod(String, BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) and call GetParameters on the returned MethodInfo.

Examples

The code sample below illustrates the use of GetParameters to discover information on the parameters passed to a dynamically-generated method.

TypeBuilder^ myType1 = myModBuilder->DefineType( "MyMathFunctions", TypeAttributes::Public );
array<Type^>^temp0 = {Type::GetType( "System.Int32&" ),int::typeid};
MethodBuilder^ myMthdBuilder = myType1->DefineMethod( "AddToRefValue", MethodAttributes::Public, void::typeid, temp0 );
ParameterBuilder^ myParam1 = myMthdBuilder->DefineParameter( 1, ParameterAttributes::Out, "thePool" );
ParameterBuilder^ myParam2 = myMthdBuilder->DefineParameter( 2, ParameterAttributes::In, "addMeToPool" );

// Create body via ILGenerator here, and complete the type.
array<ParameterInfo^>^myParams = myMthdBuilder->GetParameters();
Console::WriteLine( "Method: {0}", myMthdBuilder->Name );

for each (ParameterInfo^ myParam in myParams)
{
   Console::WriteLine("------- Parameter: {0} {1} at pos {2}, with attribute {3}", 
      myParam->ParameterType, myParam->Name, myParam->Position,
            myParam->Attributes.ToString());
}


TypeBuilder myType1 = myModBuilder.DefineType("MyMathFunctions",
                TypeAttributes.Public);

MethodBuilder myMthdBuilder = myType1.DefineMethod("AddToRefValue",
                MethodAttributes.Public,
                typeof(void),
                new Type[] { Type.GetType("System.Int32&"),
                         typeof(int) });
ParameterBuilder myParam1 = myMthdBuilder.DefineParameter(1,
                ParameterAttributes.Out,
                "thePool");
ParameterBuilder myParam2 = myMthdBuilder.DefineParameter(2,
                ParameterAttributes.In,
                "addMeToPool");

// Create body via ILGenerator here, and complete the type.

ParameterInfo[] myParams = myMthdBuilder.GetParameters();

Console.WriteLine("Method: {0}", myMthdBuilder.Name);

foreach (ParameterInfo myParam in myParams)
    {
   Console.WriteLine("------- Parameter: {0} {1} at pos {2}, with attribute {3}",
             myParam.ParameterType, myParam.Name, myParam.Position,

          MethodAttributes.Public, Nothing, _
          New Type() {Type.GetType("System.Int32&"), GetType(Integer)})

Dim myParam1 As ParameterBuilder = myMthdBuilder.DefineParameter(1, _
                  ParameterAttributes.Out, "thePool")

Dim myParam2 As ParameterBuilder = myMthdBuilder.DefineParameter(2, _
                  ParameterAttributes.In, "addMeToPool")

' Create body via ILGenerator here, and complete the type.

Dim myParams As ParameterInfo() = myMthdBuilder.GetParameters()

Console.WriteLine("Method: {0}", myMthdBuilder.Name)

Dim myParam As ParameterInfo
For Each myParam In  myParams
   Console.WriteLine("------- Parameter: {0} {1} at pos {2}, with attribute {3}", _
