我需要帮助设置/更改我的C#程序中的标签的值,每当我尝试它时发生错误,说我需要交叉线程.任何人都可以编写一些代码来帮助我吗？我的代码是:

int number = 0;
int repeats = Convert.ToInt32(textBox2.Text);

while (number < repeats)
{
   repeats++;
   label5.Text = "Requested" + repeats + "Times";
}

谁能帮我？谢谢.

我一直在互联网上寻找以下错误的解决方案;

"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'primary, username, password, password2) VALUES (null, 'hello', 'hello', 'hello')' at line 1"

我不知道发生了什么......我知道你会问我的代码是什么:

$con = mysql_connect("localhost","root","*****");
    if (!$con)
      {
      die('Server overload, please try again' . mysql_error());
      }

    mysql_select_db("users", $con);

    $sql = "INSERT INTO details (primary, username, password, password2) VALUES (null, '$_POST[username]', '$_POST[password]', '$_POST[password2]')";

    if (!mysql_query($sql,$con))
      {
      die('Error: Server overload, try again' . mysql_error());
      } …
