获得服务器路径
string path = Server.MapPath("~/bc/");<br /> if (!Directory.Exists(path))<br /> {<br /> Directory.CreateDirectory(path);<br /> }<br /> path += FileUpload1.FileName;<br /> FileUpload1.SaveAs(path);

另一种方法网上找的 js取得客户端路径
<html xmlns="http://www.w3.org/1999/xhtml"><br /> <head runat="server"><br /> <title></title><br /> <!--获取文件上传地址--><br /> <mce:script type="text/javascript"><!--<br /> function checkFile()<br /> {<br /> //判断浏览器类型<br /> var isIE = (document.all) ? true : false;<br /> var isIE7 = isIE && (navigator.userAgent.indexOf('MSIE 7.0') != -1);<br /> var isIE8 = isIE && (navigator.userAgent.indexOf('MSIE 8.0') != -1);</p> <p> var file=document.getElementById("UpLoadBorrow");<br /> var path=file.value;<br /> if(isIE7 || isIE8)<br /> {<br /> file.select();<br /> path=document.selection.createRange().text;<br /> document.selection.empty();<br /> }<br /> document.getElementById("txtFilePath").value=path;<br /> }<br /> function checkNull()<br /> {<br /> var path=document.getElementById("txtFilePath").value;<br /> if(path=="" ||path==null)<br /> {<br /> alert('请选择要上传的文件!');<br /> return false;<br /> }<br /> return true;<br /> }</p> <p>// --></mce:script></p> <p></head><br /> <body style="background-color:#0099FF;" mce_style="background-color:#0099FF;"><br /> <form id="form1" runat="server"><br /> <div style="margin:0px auto 0px auto;" mce_style="margin:0px auto 0px auto;"><br /> <asp:Image ID="Image1" runat="server" BorderStyle="Double" Width="750" ImageAlign="Middle" AlternateText="上传"/><br /> <br /><br /> 上传:<asp:FileUpload ID="UpLoadBorrow" runat="server" Height="22px" onchange="checkFile()" onkeydown="event.returnValue=false;" onpaste="return false" /><br /> <input type="hidden" id="txtFilePath" runat="server" />//这里建立一个隐藏域 用来存地址<br /> <asp:Button ID="btnUpload" runat="server" Text="上传" OnClientClick="return checkNull()" OnClick="btnUpLoad_Click" /><br /> <asp:Button ID="btnBack" runat="server" Text="返回" onmousedown="window.close();" /></div></p> <p> </form><br /> </body><br /> </html>
取值
string inputPath = txtFilePath.Value.Trim();
