I have an object[] which I am using to dynamically invoke a method via reflection. Due to an AmbiguousMatchException I need to know the types, and it would be difficult to know them ahead of time. So I want to take the "params object[] args" and get a Type[] of all of those.

Are you using DynamicInvoke? And I'm not sure how knowing the types would help since the you still need to decide between the ambiguous methods.CodesInChaos– CodesInChaos2011-01-17 22:27:16 +00:00Commented Jan 17, 2011 at 22:27

If you have linq available you can easily get an array of types that matches the objects but I'm not exactly sure it will help in your end goal.
var types = args.Select(arg => arg.GetType()).ToArray();
Is it your intention to inspect the object array for types and then inspect the method signature and try to match them up appropriately?

@CodeInChaos true...but his other code that does the dynamic invoking would not work either...
Please try this:
IList<Type> typeList = new List<Type>();
foreach(object item in args)
{
typeList.Add(item.GetType());
}
typeList.ToArray();

Give the Array.ConvertAll function a shot:
Type[] objTypes = Array.ConvertAll<object, Type>(
objArray,
delegate(object obj){
if(obj==null) return null;
return obj.GetType();
});
