I have the typename of a form I wish to to load dynamically
(example:MyCompany.Client.Win.Security.Detail.SysU serDetailForm).
However, when I call Type.GetType(typeName) it return null I am assuming
since I did not use the full name which is not available. I wrote the below
method to return the Type but I have some concerns with it.
First is there an eaiser way to do this that I am missing. Second, I am
concerned about the Assembly.Load(assemblyName); call am I loading the
referenced assembly or another instance of the same assembly?
Thanks

if (type.FullName.Equals(typeName))
{
if (result == null)
result = type;
findCount++;
}

root.GetReferencedAssemblies())

Assembly referencedAssembly = Assembly.Load(assemblyName);
foreach (Type type in referencedAssembly.GetTypes())

{

result = type;

}
}
}
if (findCount 0)
throw new Exception(string.Format("An ambiguous type error
has occurred in the method FindType. More that one Type exists with the
name {0}.", typeName));
return result;
}
