什么/bin/sh -c意思？怎么-c办？

编译C程序后,我可以获取二进制可执行文件,并在没有加载gcc的另一个系统上运行它,比如Ubuntu盒子吗？

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
    Dim LoginChecker As New SqlDataSource()
    LoginChecker.ConnectionString = ConfigurationManager.ConnectionStrings("A1ConnectionString1").ToString()
    LoginChecker.SelectCommandType = SqlDataSourceCommandType.Text
    LoginChecker.SelectCommand = "SELECT username FROM A1login WHERE username=@username AND password=@password"
    LoginChecker.SelectParameters.Add("username", username.Text)
    LoginChecker.SelectParameters.Add("password", password.Text)
    Dim rowsAffected As Integer = 0
    Try
        rowsAffected = LoginChecker.<what i have to write here>
    Catch ex As Exception
        'Server.Transfer("LoginSucessful.aspx")
    Finally
        LoginChecker = Nothing
    End Try
    username.Text = rowsAffected
    ' If rowsAffected = 1 Then
    'Server.Transfer("A1success.aspx")
    '   Else
    'Server.Transfer("A1failure.aspx")
    '  End If

End …
