Question

In c#, I use a decimal out DbParameter for a Sql Server stored procedure. I create parameter like that

---

DbParameter prm = comm.CreateParameter();  prm.ParameterName = '@Price';  prm.DbType = DbType.Decimal;  prm.Direction = ParameterDirection.Output;  comm.Parameters.Add(prm);  //and set the value of comm.Parameters['@Price'] to a variable,  decimal.TryParse(comm.Parameters['@Price'].Value.ToString(),    out this.ProdPrice); 

---

But the value of the out parameter is allways rounded.

If i call the same stored procedure from Sql Server Management Studio, i can get this out parameter properly with it’s precision

There is not a precision or scale properties on DbParameter. And i have to use DbParameter on System.Data.Common namespace for fetching the data

How can i being able to retieve decimal value with its full precision

Thanks in advance…

Adding to Marc’s suggestion, you can change the code to

IDbDataParameter prm = comm.CreateParameter();

Rest of the code should work fine. Precision and Scale properties are ‘explicit interface implementation’ in DbParameter.
