要连接网络对接数据库,可以使用以下步骤:
Imports System.Data.SqlClient
Dim connectionString As String = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;"
Dim connection As New SqlConnection(connectionString)
connection.Open()
Dim sql As String = "SELECT * FROM myTable"
Dim command As New SqlCommand(sql, connection)
Dim reader As SqlDataReader = command.ExecuteReader()
While reader.Read()
'处理查询结果的逻辑
End While
reader.Close()
connection.Close()
以上是基本的连接网络对接数据库的步骤,具体的操作可以根据实际需求进行调整和扩展。
