Question

Excel文件存储在azure blob容器中。它们在IE中没有任何意外下载，但在Chrome中页面显示此消息（并在Canary中崩溃）：

This file appears corrupt

并提供了一个下载它的链接，从那时起一切都很顺利。我尝试将内容类型设置为不同的excel格式，但结果是一样的。

这是blob代码：

  MemoryStream memoryStream = new MemoryStream();
  CreateFile(memoryStream, grid);
  memoryStream.Position = 0;
  var blockBlob = container.GetBlockBlobReference(randomFileName);
  blockBlob.Properties.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
  blockBlob.DeleteIfExists();

  var options = new BlobRequestOptions()
  {
      ServerTimeout = TimeSpan.FromMinutes(10)
   };

   try
   {
            blockBlob.UploadFromStream(memoryStream, null, options);
   }
   catch (Exception e)
   {
       _logger.Error("Uploading excel file: Error: {0}",  e.Message);
   }


   return new Uri("https://myblobs.blob.core.windows.net/" + "containername/" + randomFileName);

您错过了blockBlob.SetProperties();

试试这个：

   var blockBlob = container.GetBlockBlobReference(randomFileName);
   blockBlob.DeleteIfExists();
   blockBlob.Properties.ContentType = 
        "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
   blockBlob.SetProperties(); // This is for commiting changes.

请注意，对于.xls个文件，您需要将content-type设置为application/vnd.ms-excel。

仅供参考：如果要更新现有blob中的属性值，则需要获取当前值，设置我们要更新的属性并在BLOB上调用SetProperties。

示例：

    blob.FetchAttributes();
    blob.Properties.ContentType = "image/png";
    blob.SetProperties();

Excel文件（azure blob）不会以chrome格式下载
