Question

我打算检查我的数据库是否连接到vb.net中的项目，但似乎我的代码或SQL服务器上存在问题。它总是向我显示一条消息“用户登录失败'id / id2'”。

这是我的代码：

Imports System.Data.SqlClient
Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim sqlconn As New SqlConnection
    sqlconn.ConnectionString = "server = (local);Database=OJT;integrated security=true"
    Try
        sqlconn.Open()
    Catch ex As Exception
        MessageBox.Show(ex.Message, "Connection to Sql Server Failed!", MessageBoxButtons.OK)
    End Try
    Me.Text = "You are successfully connected to Sql Server"
End Sub
End Class

Answer 1

试试这个

sqlconn.ConnectionString = "Data Source=(local);Initial Catalog=OJT;Integrated Security=True"

Answer 2

试试这个：

"Data Source=(local);Initial Catalog=OJT;Persist Security Info=True;User ID=(Your User ID);Password=(Your Password)"

希望它能解决你的问题。美好的一天！
