学生（sid，sname，smarks，saddress）//这里我们从XML插入到DB
master_table（sid，sname，age，gender）这些r这两个表
这里我想再检查一下，比如，如果XML文件中的sid不在master_table中，那么我想用不同的颜色显示那些在网格视图中，当我点击显示按钮。

推荐答案
只需在sqlcommand中使用select查询。
并使用dataReader。
sqldatareader dr = cmd.executereader（）; //（cmd是Sqlcommand的对象）
if（dr.read（））
{
//在这里使用你的代码
}
just use select query in sqlcommand.
and use dataReader.
sqldatareader dr = cmd.executereader(); //(cmd is object of Sqlcommand)
if (dr.read())
{
//use your code here
}
