C#中导致拼接字符串无效

sql += "'" + col.Table.Rows[tabParams.Rownum][col.Ordinal].ToString()+ "',";

使用for循环对SQL语句进行拼接的时候，循环到某个字段，不管怎么自加字符串的值都不变，得到的SQL语句是不完整的，如下

insert into jk_sample (FBMMC,FGZJH,FSBMC,FSBBH,FSBXH,x_Number,x_Name,x_Method,Weight,Moisture,SulfurArea,SulfurPeak,SulfurTime,Stad,Std,x_Date,x_Operator,Memo,initVolt,lparam,x,y) 

values('化学室','222','全自动测硫仪','03','5E-IRS3600','20200226045','A0588782','20191210','0.2968','0.68','3.32760320899911','0.105281323418624','154','2.47854333257062','2.47854333257062','2020/2/26 18:05:40','

后来查了一些网上的资料得知代表字符串的终止，而循环到的那个字段值就是。

C#对字符串自加，末尾出现，就会终止对此字符串的所有操作

因此需要将字符替换掉，就可以对字符串正常操作了

sql += "'" + col.Table.Rows[tabParams.Rownum][col.Ordinal].ToString().Replace("","") + "',";

insert into jk_sample (FBMMC,FGZJH,FSBMC,FSBBH,FSBXH,x_Number,x_Name,x_Method,Weight,Moisture,SulfurArea,SulfurPeak,SulfurTime,Stad,Std,x_Date,x_Operator,Memo,initVolt,lparam,x,y)
