Tried creating anonymous types and changing its value ?? Its strange, but Anonymous types in C# are readonly.
var v = new { FName = "aaa" , LName = "bbb" };
v.FName = "aaaa";
Above lines of code would yield following error
"Property or indexer 'AnonymousType#1.FName' cannot be assigned to -- it is read only"
But ofcourse, there is a workaround, you can use reflection to change the value of the Anonymous Method.
Type t = v.GetType();
FieldInfo fi = t.GetField( "
fi.SetValue(v, "1234");
Its true that the power of reflection cannot be ignored no matter what new features are added to .Net framework.
