     email1 = Convert.ToString(cleanedEmailTbl.Rows[i][2]);
     email2 = Convert.ToString(cleanedEmailTbl.Rows[i][3]);
     Website = Convert.ToString(cleanedEmailTbl.Rows[i][4]);

请帮帮我.
它花费了超过一分钟的时间，然后引发异常.

Please help me.
It takes more than one minute and then throws an exception.

推荐答案

您确实应该考虑使用StringBuilder来构建字符串，因为您正在创建大量的字符串.像这样的字符串.
看看这篇文章，讨论为什么应该使用StringBuilder
字符串与StringBuilder(C#) [

You should really consider using StringBuilder to build your string, as you''re creating a massive amount of strings as like that.
Have a look at this article for a discussion of why you should use StringBuilder
String Vs StringBuilder (C#)[^]

As for your question, I''ve never heard of Context switch, is that the exception message? if so is there an inner exception which could provide more details?

如果在调试过程中遇到此异常，请尝试删除上下文切换死锁中断.

为此，请从菜单Debug/Exceptions中选择，然后打开Managed Debugging Assistants并清除Context switch ...的复选框.

If you''re getting this exception during the debugging, try removing context switch deadlock break.

In order to do this, select from the menu Debug/Exceptions and then open the Managed Debugging Assistants and clear the check box for Context switch...
