设置数据库查询的时间限制

Question

我想为某个数据库查询设置时间限制。

我该怎么做？

try
{
    using (SqlConnection connection = new SqlConnection(ConString)
    {
        using (SqlCommand command = new SqlCommand())
        {
            command.CommandText = sp;

            command.CommandType = CommandType.StoredProcedure;

            command.Connection = connection;

            command.Connection.Open();

            using (SqlDataReader reader = command.ExecuteReader())
            {
                string role = "";
                if (reader.Read())
                    role = reader.GetString(0);

                reader.Close();
            }
        }
    }
}
catch (Exception ex)
{
     //throw new Exception(string.Format("DBLayer failure in {0}: {1}", sp, ex.Message), ex);
}

将SqlCommand对象的CommandTimeout属性设置为所需的时间限制（以秒为单位）。
