如何在vb.net中调用SQL Server数据库？

Public Sub CreateCommand(ByVal queryString As String, _ ByVal connectionString As String) Using connection As New SqlConnection(connectionString) Dim command As New SqlCommand(queryString, connection) command。 Connection。Open() Dim reader As SqlDataReader = command。ExecuteReader() While reader。 ...全部

  Public Sub CreateCommand(ByVal queryString As String, _ ByVal connectionString As String) Using connection As New SqlConnection(connectionString) Dim command As New SqlCommand(queryString, connection) command。
  Connection。Open() Dim reader As SqlDataReader = command。ExecuteReader() While reader。
  Read() Console。WriteLine("{0}", reader(0)) End While End Using End Sub queryString就是你的查询泽肤串，例如 select * from 表名。
   While reader。Read() Console。WriteLine("{0}", reader(0)) End While 这个部分你可能需要替换成和datagridview绑定的代码。
   以上代码在。dotnet带的msdn帮助中都可以查到。收起
