sql += "'" + col.Table.Rows[tabParams.Rownum][col.Ordinal].ToString()+ "',";
使用for循環對SQL語句進行拼接的時候，循環到某個字段，不管怎么自加字符串的值都不變，得到的SQL語句是不完整的，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('化學室','222','全自動測硫儀','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','
后來查了一些網上的資料得知\0代表字符串的終止，而循環到的那個字段值就是\0。
C#對字符串自加，末尾出現\0，就會終止對此字符串的所有操作
因此需要將\0字符替換掉，就可以對字符串正常操作了
sql += "'" + col.Table.Rows[tabParams.Rownum][col.Ordinal].ToString().Replace("\0","") + "',";
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)
