    winform or webform?
    win: 工具箱上openfiledialog 
    web: 以上传文件时选择文件为例<form id="Form1" action="refresh" encType="multipart/form-data" runat="server">
    <P>
    <div align="center"><asp:label id="Lb1" runat="server" ForeColor="Desktop" Font-Size="Small" Font-Names="黑体" Width="248px" Height="24px"></asp:label></div>
    <asp:label id="lin" runat="server" ForeColor="Desktop" Font-Size="X-Small" Font-Names="宋体" Width="544px" Height="1px"></asp:label><asp:label id="Lsc" runat="server" ForeColor="Red" Font-Size="X-Small" Font-Names="宋体" Width="72px" Height="1px" Visible="False"></asp:label>
    <P></P>
    <P>选择上传文件: <input id="File1" type="file" size="50" name="File1" runat="server">
    </P>
    <P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<INPUT id="Button1" style="WIDTH: 72px; BORDER-TOP-STYLE: ridge; BORDER-RIGHT-STYLE: ridge; BORDER-LEFT-STYLE: ridge; HEIGHT: 24px; BACKGROUND-COLOR: transparent; BORDER-BOTTOM-STYLE: ridge" type="button" value="执行上传" name="Button1" runat="server" OnServerClick="ExecUpload">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

    <TABLE id="Table2" style="Z-INDEX: 101; LEFT: 112px; WIDTH: 525px; POSITION: absolute; TOP: 150px; HEIGHT: 38px" height="38" cellSpacing="1" cellPadding="1" width="525" align="center" border="1">
    <TR>
    <TD><IMG id="imgg" alt="" src="" align="middle" runat="server"></TD>
    </TR>
    </TABLE>
    </form>
    /////////////////////////////////////////
       File1.PostedFile.SaveAs(Lsc.Text)
       imgg.Src = File1.PostedFile.FileName()
