ADO.NET DataService record count

I have stored some records in to database using ADO.NET Entity Framework. I want to know total record count in particular table using ADO.NET Entity Framework in C#.Net .

I given some example, but it is not working.

  EX:
  DataServiceQuery<BunHistory> query= context.BunHistory.IncludeTotalCount();
  QueryOperationResponse<BunHistory> response                                         
                        query.Execute() as QueryOperationResponse<BunHistory>;
  long count = response.开发者_JS百科TotalCount;

When i run this code i got some exception "An error occurred while processing this request." like this.

Thanks

int count = context.table.Count();

EDIT:

It is becoming apparent that you are actually querying an ADO.Net DataService. While the backend may be EF, the API you are trying to get a count from is not.

The code you added looks correct. I am going to assume that the problem is not in the syntax.

At what point do you get the error?

You can get more information about the error so that you know exactly what point the error is happening - http://blogs.msdn.com/phaniraj/archive/2008/06/18/debugging-ado-net-data-services.aspx

Hope this helps.
