这就是我想要使用的;

string insertQuery = @"insert into userinfo (UserName, FirstName, LastName, 
                      E-mail, Password,  Country) 
                      values ( '" + uname + "', '" + fname + 
                      "','" + lname + "', '" + email + "')";

其中+之间的每个变量都是带有值的字符串变量.但是当我运行此命令时,我得到一些不正确的语法错误.

这是我得到的新错误;
