System.Data.SqlClient.SqlException：用户“”登录失败

Question

我正在尝试在网络上运行我的实体框架模型。

这是我的连接字符串：

connectionString="metadata=res://*/EmployeeModel.csdl|res://*/EmployeeModel.ssdl|res://*/EmployeeModel.msl;provider=System.Data.SqlClient;provider connection string="data source=BTC-L8LBXTY1-2\MSSQLSRVER2014;initial catalog=Test;integrated security=False;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient"

我没有用于连接字符串的用户名或密码，但是其他一些帖子说它可能是其中之一？

这是我收到的错误的堆栈跟踪：

我在连接字符串中添加了与此参数匹配的用户名和一个空密码的参数。

Answer 1

您可以使用Windows凭据登录集成security = true来登录，或者在连接字符串中添加用户名和密码，只需添加用户并添加详细信息
