使用Windows身份验证连接到SQL Server [英] Connecting to SQL Server using windows authentication

问题描述

当我尝试使用以下代码连接到SQL Server时:

When I was trying to connect to SQL Server using the following code:

SqlConnection con = new SqlConnection("Server=localhost,Authentication=Windows Authentication, Database=employeedetails");
con.Open();
SqlCommand cmd;
string s = "delete employee where empid=103";

我收到以下错误:

建立与SQL Server的连接时发生与网络相关或特定于实例的错误.服务器未找到或无法访问.验证实例名称正确，并且已将SQL Server配置为允许远程连接. (提供者:SQL网络接口，错误:25-连接字符串无效)

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: SQL Network Interfaces, error: 25 - Connection string is not valid)

推荐答案

SQL Server的连接字符串应类似于:"Server= localhost; Database= employeedetails; Integrated Security=True;"

A connection string for SQL Server should look more like: "Server= localhost; Database= employeedetails; Integrated Security=True;"

如果您有SQL Server的命名实例，则还需要添加它，例如"Server=localhost\sqlexpress"

If you have a named instance of SQL Server, you'll need to add that as well, e.g., "Server=localhost\sqlexpress"
