c# - 无法上传大小超过 5000 k 的 zip 文件

Question

我是 C# 的新手，我能够上传一个较小的文件到服务器 但是当我尝试上传超过 5000k 的大小时，它给出了一个异常(exception)。

这是我的C#代码

private void UploadFile(string filename)
{
  try
  {
    PeopleMatrixService peopleMetrixService = new PeopleMatrixService();

    String strFile = System.IO.Path.GetFileName(filename);
    // TestUploader.Uploader.FileUploader srv = new TestUploader.Uploader.FileUploader();
    FileInfo fInfo = new FileInfo(filename);
    long numBytes = fInfo.Length;
    double dLen = Convert.ToDouble(fInfo.Length / 10000000);
    if (dLen < 8)
    {
      FileStream fStream = new FileStream(filename, FileMode.Open, FileAccess.Read);
      BinaryReader br = new BinaryReader(fStream);
      byte[] data = br.ReadBytes((int)numBytes);
      br.Close();
      string sTmp = peopleMetrixService.UploadFile(data, strFile);
      fStream.Close();
      fStream.Dispose();
      MessageBox.Show("File Upload Status: " + sTmp, "File Upload");
    }
    else
    {
      MessageBox.Show("The file selected exceeds the size limit for uploads.", "File Size");
    }
  }
  catch (Exception ex)
  {
    MessageBox.Show(ex.Message.ToString(), "Upload Error");
  }
}

和我在网络服务中的代码

[WebMethod]
public string UploadFile(byte[] f, string fileName)
{
  try
  {
    MemoryStream ms = new MemoryStream(f);
    FileStream fs = new FileStream(System.Web.Hosting.HostingEnvironment.MapPath("~/Response Attachments/") + fileName, FileMode.Create);
              //FileStream fs = new FileStream(Server.MapPath("~/Response Attachments/") + fileName, FileMode.Create);
    ms.WriteTo(fs);
    ms.Close();
    fs.Close();
    fs.Dispose();
    return "OK";
  }
  catch (Exception ex)
  {
    return ex.Message.ToString();
  }
}

默认情况下，maxRequestLength 设置为 4096 (4mb)，您需要在 web.config 文件中将其更改为更大的大小。
