vb.net 读取数据库

您好！感谢您对ChitGPT的使用。针对您的问题，可以使用以下代码来实现VB.NET读取数据库：

Dim connectionString As String = "Data Source=serverName;Initial Catalog=DBName;User ID=userID;Password=password"
Dim connection As New SqlConnection(connectionString)
Dim sql As String = "SELECT * FROM TableName"
Dim command As New SqlCommand(sql, connection)
connection.Open()
Dim reader As SqlDataReader = command.ExecuteReader()
While reader.Read()
    Dim column1 As String = reader.GetString(0)
    Dim column2 As Integer = reader.GetInt32(1)
    '读取其他列'
End While
connection.Close()

请注意替换数据源、数据库名称、用户名和密码以及表名称和列名，在使用之前请确保已安装适当的数据库驱动程序。希望这可以帮助您解决您的问题！
