我正在try 覆盖默认的SqlConnection超时(15秒)，但收到一个错误，指出
无法分配属性或索引器，因为它是只读的.
有办法吗？
using (SqlConnection connection = new SqlConnection(Database.EstimatorConnection))
{
connection.Open();
using (SqlCommand command = connection.CreateCommand())
{
command.CommandType = CommandType.StoredProcedure;
connection.ConnectionTimeout = 180; // This is not working
command.CommandText = "sproc_StoreData";
command.Parameters.AddWithValue("@TaskPlanID", order.Projects[0].TaskPlanID);
command.Parameters.AddWithValue("@AsOfDate", order.IncurDate);
command.ExecuteNonQuery();
}
}
