I wish did fix the issue. I can't get TryGetValue to work for some reason. , Add this line after creating the dictionary:
code :
String value = "";

To fix this issue This is one of the more confusing points of Entity Framework. What you have to realize is that ObjectContext is the old way of doing EntityFramework, circa 2010. This was before DbContext (and code first). You can still get to the ObjectContext by casting your DbContext to IOjbectContextAdapter, like this:
code :
((IObjectContextAdapter)context).ObjectContext;
ObjectQuery<Person> persons = new ObjectQuery<Person>(cmd, ((IObjectContextAdapter)context).ObjectContext);
var firstname = "Fred";
return from person in AWEntities.Person
       where person.FirstName = firstname
       select person;

this one helps. txt_Name.ToString resolves to a method group that refers to the ToString method. It doesn't call ToString. To do that you would need to write txt_Name.ToString(). Having said that, you don't want to do that either. The ToString method of TextBox does not return the text of the control. The Text property is how you get the text, so you want to write: txt_Name.Text.
Finally, you should avoid functions with so many arguments. It makes it much harder to try to determine what's wrong when you have the error that you are seeing when there are so many arguments; there are just so many ways that it could be off. Instead RegistrationClass should simply have properties of each of those values, and then the caller can set each property individually. This will be quite a lot easier to work with.

hope this fix your issue , Here is the mistake :
code :
decimal ans = Summary_Matrics_Client.getall(dpmo);
decimal ans = Summary_Matrics_Client.getall(ref dpmo);
public static decimal getall(decimal? number)
decimal ans = Summary_Matrics_Client.getall(dpmo);

Hope this helps string.Contains() wants a string, and you are giving it a char.
Try this instead:
