如何使用C＃訪問dll？

Question

我在VB中有一個使用dll搜索數據庫的舊應用程序中的代碼。 您能告訴我如何在C＃中做到嗎。

Pseek是dll

Dim SeekForm As New PSeek.cSeek
            Dim redRow As mscomctl.ListItem
            Dim succ As Long
            Try
                redRow = Nothing
                succ = SeekForm.CallSeekForm(My.Settings.PSeekConnectionString, "SELECT id,naziv,adresa,broj,vlez,stan,mesto from vSifrarnik where Firmaid = " & My.Settings.curFirma & " and Siftipid=" & SifTipIDUltraCombo.Value, "id,naziv,adresa,broj,vlez,stan,mesto", redRow, 1, , True, False)
                If Not (redRow) Is Nothing Then
                    SifraIDUltraTextEditor.Text = redRow.Text
                    SifraIDUltraTextEditor.Focus()
                End If
            Catch ex As System.Exception
                System.Windows.Forms.MessageBox.Show(ex.Message)
            End Try

添加dll文件，方法是右鍵單擊您的項目，然后添加引用並選擇dll文件。 然后在您的代碼類型

using LibraryName;
