************** JIT调试************* *
要启用即时（JIT）调试，此
应用程序或计算机（machine.config）的.config文件必须具有
jitDebugging值在system.windows.forms部分设置。
应用程序也必须使用调试编译
启用。
例如：
< configuration>
< system.windows。表格jitdebugging =true>
启用JIT调试后，任何未处理的异常
将被发送到计算机上注册的JIT调试器
而不是被这个对话框处理。
我试过的：
< configuration>
< system.windows.forms jitdebugging =true>
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitdebugging="true">
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
What I have tried:
<configuration>
<system.windows.forms jitdebugging="true">
推荐答案
阅读错误消息：
Read the error message:
System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
它甚至可以告诉您确切要做什么以及要检查什么！ />
请查看代码，找到创建SqlConnection的位置并查看连接字符串。几乎可以肯定，这是错误的。
It even tells you exactly what to do and what to check!
So look at your code, find where you create the SqlConnection and look at the connection string. Almost certainly, it's wrong.
请检查你的连接字符串并确保连接字符串中提供的用户名和密码是正确的。
Please check your connection string and make sure that the username and password provided in connection string is correct.
在SQL中Server 2008您可以通过打开SQL Server 2008 Management Studio，连接到相关服务器，右键单击服务器并打开服务器属性。导航到Connections并确保选中允许与此服务器的远程连接。检查这是否解决了问题。
In SQL Server 2008 you do this by opening SQL Server 2008 Management Studio, connect to the server in question, right click the server and open the Server Properties.Navigate to Connections and ensure that Allow remote connections to this server is checked. Check if this solves the problem.
