另附上js的提示的换行写法：

alert("您确定提交整个问卷吗？\n\n提交后将不能再填写各个工种的用工需求，整个问卷将就此结束！")

confirm("您确定提交整个问卷吗？\n\n提交后将不能再填写各个工种的用工需求，整个问卷将就此结束！")

判断文件是否存在，如存在并将其删除

public static bool IsExistsFile(string FilePath)

{

if (File.Exists(FilePath) == true)

{ 

//****删除文件

File.Delete(FilePath);

return true;

}

return false;
