Question

I am trying to dynamically get the default for a type that is specified in a ParameterInfo. _methods[methodName] returns a MethodInfo object.

Unfortunately, the compiler doesn’t like the "paramType" bit inside the default(paramType). I’m stumped.

Error

The type or namespace name ‘paramType’ could not be found (are you missing a using directive or an assembly reference?)

C:\Applications\…\MessageReceiver.cs Line 113

Example

object blankObject = null; foreach (var paramInfo in _methods[methodName].Key.GetParameters()) {     if (paramInfo.Name == paramName)     {         Type paramType = paramInfo.ParameterType;         blankObject = (object)default(paramType);     } } parameters[i] = blankObject;

It’s quite simple to implement:

public object GetDefault(Type type) {     return type.IsValueType ? Activator.CreateInstance(type) : null; }
