问题描述
我正在尝试通过asp.net连接到postgresql数据库，但即使在正确编写代码后也会反复出现此错误。任何人都可以帮我解决这里的解决方案是我的代码？ ： -
Private Sub Button1_Click（ByVal sender As System.Object，ByVal e As System.EventArgs）Handles Button1.Click
Dim con作为NpgsqlConnection
con =新的NpgsqlConnection（server = localhost; port = 5432; userid = mayank; password = manager; database = postgres）
con.Open（）
MsgBox（已打开）
结束次级
错误我得到的是： -
无法加载文件或程序集'Mono.Security，Version = 1.0.5000.0，Culture = neutral，PublicKeyToken = 0738eb9f132ed756'或其中一个它的依赖关系。定位的程序集的清单定义与程序集引用不匹配。 （来自HRESULT的异常：0x80131040）
我已添加monosecurity.dll作为参考但尚未连接到postgresql db ... m使用npgsql驱动程序连接到postgresql数据库
