分享蛙蛙请教:出错提示"并非所有的代码路径都返回值"
蛙蛙请教:出错提示"并非所有的代码路径都返回值"
我在类里写了个静态方法,用来上传东西,但是老是调试不成功,大家给看看,谢谢
public static string upfile(System.Web.UI.Page p,System.Web.UI.HtmlControls.HtmlInputFile file1){
if (file1.PostedFile != null)
{
try
{
string spath=p.Server.MapPath(p.Request.ApplicationPath)+ConfigurationSettings.AppSettings["uppath"]+oa.cls.globalstate.MakeRand(10)+System.IO.Path.GetFileName(file1.PostedFile.FileName);
file1.PostedFile.SaveAs(spath);
return spath;
}
catch (Exception exc)
{
throw exc;
}
}
出错提示:
E:\me\web.net\oa\cls\globalstate.cs(134): “oa.cls.globalstate.upfile(System.Web.UI.Page, System.Web.UI.HtmlControls.HtmlInputFile)” : 并非所有的代码路径都返回值
