喜Elanchezian，这个代码是对你有帮助对于MD5哈希在C＃使用此方法。 {C}关于Sudheer.N
Anuja帕瓦尔多尔:约翰给予正确的解决方案，您可以在SQL查询，这也

密码字段中应输入的二进制格式。时获取记录，然后再转换为字符串格式。尝试，它会更快

NBSP
解决方案1:

如果您的SQL服务器是SQL Server身份验证，然后只使用下面的ConnectionString { BR}


LT; AppSettinggt;
LT添加关键的ConnectionString值="数据访问此
NBSP的ConnectionString;
使用System.Configuration;
字符串str = ConfigurationManager.AppSettings ["的ConnectionString"]

解决方案2:
NBSP
，如果您的SQL服务器是Windows身份验证，那么就使用后的ConnectionString
NBSP

LT添加关键的ConnectionString;价值= "数据源=服务器名称，数据库= DatabaseName的集成安全性=假"GT
LT ;/ AppSettinggt


使用System.Configuration;
字符串str = ConfigurationManager.AppSettings ["的ConnectionString"]


我认为这将解决这个问题...
