C# 多用户正在访问Zip文件-Mem出异常问题,c#,asp.net-mvc-3,download,C#,Asp.net Mvc 3,Download,这就是我目前所知道的在我看来 @foreach (var file in item.AssociatedFileList) { @Html.ActionLink(file.FileName, "GetFile", "Landing", new { path = file.FilePath }, new { target = "_blank" }) <br /><br /> } 后来我检查了filestream OIObject的文件大小，它是108

这就是我目前所知道的

在我看来

@foreach (var file in item.AssociatedFileList)
{      
    @Html.ActionLink(file.FileName, "GetFile", "Landing", new { path = file.FilePath }, new { target = "_blank" }) <br /><br />
}

后来我检查了filestream OIObject的文件大小，它是108560843

我把我能想到的一切都放在这个问题上。这是我第一次使用文件，我不想错过任何细节。

禁用页面检查器。如何禁用页面inst从“运行”旁边的下拉列表中取消选中“启用浏览器链接”。哇，现在可以使用了，谢谢。页面检查器对我的代码做了什么，但它不起作用。它试图在内存中缓冲整个文件。

public ActionResult GetFile(string path)
    {
        var extension = Path.GetExtension(path);
        FileStream fs = new FileStream(path, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);

        if (extension == ".pdf")
            return File(fs, "application/pdf", Path.GetFileNameWithoutExtension(path));

        if (extension == ".xlsx" || extension == ".xls")
            return File(fs, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", Path.GetFileNameWithoutExtension(path));

        if (extension == ".zip")
            return File(fs, "application/zip", Path.GetFileNameWithoutExtension(path));                       

       return this.Content("<html><center><span style='font-size: large; font-weight: bold; font-family: 'Century Gothic', 'PT Sans', 'Verdana', 'Arial', 'Helvetica', 'sans-serif'; color: #FF0000;'>There is no file to view<span></center></html>");
    }

@Html.ActionLink(file.FileName, "GetFile", "Landing", new { path = file.FilePath }, new { target = "_blank" }) <br /><br />
