的SQLConnection代码

Question

当试图建立我得到下面的异常的连接：

System.Data.SqlClient.SqlException occurred 
    HResult=0x80131904 
    Message=Login failed for user ''. 
    Source=.Net SqlClient Data Provider 
    StackTrace: 
<Cannot evaluate the exception stack trace> 

我不断收到上述错误，这里是我的代码：

SqlConnection conn = 
    new SqlConnection(@"Data Source = Computer-DELL\SQLEXPRESS;Initial Catalog = Drivers"); 

conn.open(); 

Answer 1

您的连接字符串没有用户名和密码和或集成安全性。

具有集成安全：

Data Source=localhost\SQLSERVER;Initial Catalog=YourDataBaseName;Integrated Security=True; 

用户名和密码：

Data Source=localhost\SQLSERVER;Initial Catalog=YourDataBaseName;persist security info=True;user id=someusername;password=somepassword; 

Answer 2

假设他们有权限，本地用户：

SqlConnection conn = new SqlConnection(@"Data Source = Computer-DELL\SQLEXPRESS;Initial Catalog = Drivers;Trusted_Connection=True;") 
conn.open();
