.aspx 页面中的 SqlDataSource 连接字符串
我有一个将 ASP.NET 页面部署到 SharePoint 的解决方案，该解决方案在一些页面上使用 SqlDataSources。由于在 SharePoint 部署中，与我们的应用程序（部署到 GAC）关联的 web.config 文件是 SharePoint 服务器的 web.config，因此我们没有对所有环境的完全访问权限来更改 web.config 文件并添加连接字符串。然后，我尝试创建一个带有连接字符串变量的全局密封类，并希望在 aspx 页面上设置连接字符串。我知道这可以在后面的代码中完成，但想知道是否有办法在 aspx 页面的标记中设置它？
前任。
ConnectionString='<% CompanyABCGlobal.DBConnectionString %>'
尝试执行上述操作时出现以下错误： 初始化字符串的格式不符合从索引 0 开始的规范。
要在代码隐藏中执行此操作，我需要为每个 SqlDataSource 声明一个受保护的属性，然后为每个 SqlDataSource 设置连接字符串属性。
感谢您的任何反馈。
I have a solution for ASP.NET pages to be deployed to SharePoint that uses SqlDataSources on a few of the pages. Since with the SharePoint deployment the web.config file that is associated with our application (deployed to GAC) is the web.config for the SharePoint server, we do not have full access for all environments to change the web.config file and add connection strings. I then tried to create a global sealed class with a connection string variable and would like to set the connection string on the aspx page. I understand this could be done in code behind, but was wondering if there was a way to set it in the markup of the aspx page?
ex.
ConnectionString='<% CompanyABCGlobal.DBConnectionString %>'
I get the following error when attempting to do the above:
Format of the initialization string does not conform to specification starting at index 0.
To do this in code behind, I would need to declare a protected property for every SqlDataSource and then would set the connection string property for each one.
Thanks for any feedback.

为了访问类属性，您必须在表达式的开头使用 = 或 # 声明，即
如果您的类可从该页面获得，您可以通过在表单标记后打开 <% 表达式来测试它。
有关表达式 msdn 的详细信息
In order to access class properties you must use = or # declaration in the starting of expressions,i.e
You can test it by opening <% expression after form tag if your class is available from that page.
