在日期字符串前面加一个单引号'
追问
在建表时,我插入的日期格式是这样的,比如 ‘2013-08-13’,你所说的在日期字符串前面加一个单引号',是在建表时加呢,可是我已经有单引号了,如‘2013-08-13’,还是在哪里加呢?望解答一下,谢谢~
追答
在这里 for (int j = 1; j < das.Tables[0].Columns.Count; j++)
{
if(j==日期列)
{
tw.Write("'" +das.Tables[0].Rows[i][j].ToString()+ '\t');
}
else
{
tw.Write(das.Tables[0].Rows[i][j].ToString() + '\t');
}
}
