通常会回过来的是: 如果是的话,只是一箱子,然后转换:
(int)(byte) reader["column"];
或只是让转换自然发生:
int x = (byte) reader["column"];
或与严格分类的方法相同:
int x = reader.GetByte(column);
将这一条改为<代码>sbyte或short 或者,如果我错把它绘制成<条码>,则无论怎样。 你可以在服务器一侧进行转换,但我个人在客户方面这样做,并保持车轮。
使用“普通”处理锡奈特问题
int RetValue;
RetValue = (int)(byte)dt.Rows[A][B] // A = RowNo , B = tinyint Column Name.
a. 从一片纸张桌上提取一个小int:
retorno = Convert.ToInt32(dr.GetByte(dr.GetOrdinal("StepStatus")));
如果重新编号为无固定变量。
我希望你能这样做。
