我使用以下代码连接到sql throgh windows身份验证.

string connctionstring = "connectionString={0};Database={1};Integrated Security=SSPI;";
string _connctionstring = string.Format(connctionstring, datasource, initialCatalogue);
SqlConnection _connection = new SqlConnection(_connctionstring);
_connection.Open();

但我收到以下错误.请帮助.我可以通过sql server登录.

连接字符串格式不正确更改为:

string connctionstring = "Data Source={0};Database={1};Integrated Security=SSPI;";

要么

string connctionstring = "Server={0};Database={1};Integrated Security=SSPI;";
