Stored procedure or function expects parameter which was not supplied

Question

I am trying to insert data into a SQL Server database by calling a stored procedure, but I am getting the error

*Procedure or function \'Insertion\'

Answer 1

This is how it can be done

using (var cmd = new SqlCommand("STORED_PROCEDURE_NAME", SqlConnection))
{
     cmd.CommandType = CommandType.StoredProcedure;
     cmd.Parameters.AddWithValue("@PARAM_NAME", PARAM_VALUE);
}

Notice that AddWithValue, and CommandType.StoredProcedure both are essential.
