使用OpenFilleDailog打开文件。-.NET教程,Windows开发

    private sub button1_click(byval sender as system.object, byval e as system.eventargs) handles button1.click
        dim fdlg as openfiledialog = new openfiledialog()
        fdlg.title = "vb.net打开文件对话框的使用"
        fdlg.initialdirectory = "c:\"
        fdlg.filter = "all files (*.*)|*.*"
        fdlg.filterindex = 2
        fdlg.restoredirectory = true
        if fdlg.showdialog() = dialogresult.ok then
            textbox1.text = fdlg.filename
        end if
    end sub

附上示例的所有代码：（useopenfiledailog.vb)
public class useopenfiledialog
    inherits system.windows.forms.form

#region " windows form designer generated code "

    public sub new()
        mybase.new()

        this call is required by the windows form designer.
        initializecomponent()

        add any initialization after the initializecomponent() call

    end sub

    form overrides dispose to clean up the component list.
    protected overloads overrides sub dispose(byval disposing as boolean)
        if disposing then
            if not (components is nothing) then
                components.dispose()
            end if
        end if
        mybase.dispose(disposing)
    end sub

    required by the windows form designer
    private components as system.componentmodel.icontainer

    note: the following procedure is required by the windows form designer
    it can be modified using the windows form designer.  
    do not modify it using the code editor.
