推荐答案

有很多方法可以修改连接字符串.

0)将整个字符串保存在您的应用程序配置中.

1)将属性值保存在应用程序配置中，并根据这些值在应用程序中构造实际字符串

2)如果找不到连接字符串，或者尝试连接时遇到问题，请提示用户输入适当的属性值(服务器，初始目录，用户ID，密码等)，然后保存新的应用程序配置中的数据.

您是否使用Settings类将连接字符串存储在app.config中?

There are many ways to modify the connection string.

0) Save the entire string in your app config.

1) Save the attribute values in the app config, and construct the actual string in the application based on those values

2) If the connection string isn''t found, or if there''s a problem encountered when trying to connect, prompt the user for the appropriate attribute values (server, initial catalog, userID, password, etc) and then save the new data in the app config.

Are you using the Settings class to store the connectionstring in the app.config?
