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();
    }
}

```
