Create Object from Name

[stsuing]

Say I have the string "System.Xml.XmlException". How can I create an object from that?

object[] args = new object[2];
args[0] = "Message";
args[1] = new Exception("Inner Exception Message");

Exception fooBar = (Exception)Activator.CreateInstance(typeof(System.Xml.XmlException), args);
Console.WriteLine(fooBar.ToString());


This works, but I can't figure out how to get the type from just the string "System.Xml.XmlException".

I think that CreateTypeFromProgID might be what you are after:

http://msdn.microsoft.com/library/d...ypeclassgettypefromprogidtopic.asp?frame=true

If not, you can also use the VB CreateObject function even though you are programming in C# by referencing the Microsoft.VisualBasic assembly:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vblr7/html/vafctCreateObject.asp

Note that I believe these functions are for COM components, I'm not sure if they will work for .NET classes.

For the .NET classes, it looks like plain old GetType will work for you:

Type t = Assembly.LoadWithPartialName("System.Xml").GetType("System.Xml.XmlException");
Exception fooBar = (Exception)Activator.CreateInstance(t, args);
