Question

i have created a generic function named ExecuteProcedure<T>(T command, string parameters), now inside the ExecuteProcedure function i want to cast the T into SqlCommand, so that i can use SqlCommand's properties like Parameters.Add() here is my code.

T could be SqlCommand or SqlDataAdapter

here’s my code:

public void ExecuteProcedure<T>(T command, string parameters)
{
    using (connection)
    {
        if (typeof(T) == typeof(SqlCommand))
        {
           //how to convert into SqlCommand Here to use command.CommandType Property below.
        }
        command.CommandType = CommandType.StoredProcedure;
        foreach (string param in parameters.Split(','))
        {
            SqlParameter par = new SqlParameter(param, param.Substring(1, param.Length - 1));
            command.Parameters.Add(par);
        }


        connection.Open();
        command.ExecuteNonQuery();
    }
}

You can use this code to CAST T to SqlCommand

SqlCommand cmd = (SqlCommand)Convert.ChangeType(command, typeof(SqlCommand));
