Capture Stored Procedure print output in .NET (Different model!)

Question

Basically, this question with a difference...

Is it possible to capture print output from a TSQL stored procedure in .NET, using the Entity Framework?

The so

Answer 1

Just to show people a complete working example from Craig's answer and Wim's response:

var entityConnection = (EntityConnection)Context.Connection;
var sqlConnection = (SqlConnection)entityConnection.StoreConnection;
sqlConnection.InfoMessage += (s,a) => Debug.WriteLine(a.Message);

Answer 2

This is what worked for me, samneric's example was helpful but not the exact syntax.

string message = Empty.string;

using (var context1 = new DatabaseEntities())
            {
                var conn =
                ((EntityConnection)
                    ((IObjectContextAdapter)context1).ObjectContext.Connection);

                var sqlConnection = (SqlConnection)conn.StoreConnection;

                sqlConnection.InfoMessage += (s, a) => message = a.Message;

              data = context1.storedProc("Parameter");


            }

Answer 3

Actually, it does, but since the EF is not SQL Server specific, you have to cast it:

var sqlConn = (SqlConnection)Context.Connection.StoreConnection;

Answer 4

Based on the answer from @samneric, but with some modifications for EF Core we used this to allow debugging of a wayward stored procedure;

    DbConnection connection = Database.GetDbConnection();
    var sqlConnection = connection as SqlConnection;
    sqlConnection.InfoMessage += (s, a) => System.Diagnostics.Debug.WriteLine(a.Message);
