GetType().Assembly.CreateInstance("myUserContro") returns null

From my default.aspx pageI am trying to use reflection to create instances of user controls.

I am using the latest version of .net and Visual Studio 2008.

When I call this line I always get a null result and I cannot understand why.

this.GetType().Assembly.CreateInstance("Controls_NameAddress",true)

Your help will be greatly appreciated.

Is "Controls_NameAddress" the class that you are trying to instantiate?

Try with this
Assembly.GetAssembly(Controls_NameAddress).CreateInstance("Controls_NameAddress");
Note : instead of giving just Controls_NameAddress try with complete Namespace.classname

Another possibility is the class you are trying to instantiate is not found in the assembly. this.GetType().Assembly only refers to the assembly where the current object is declared, does not include other class libraries. A little correction to P_Ramprathap's suggestion:
Assembly.GetAssembly(typeof(Controls_NameAddress)).CreateInstance("Controls_NameAddress");
