在过去的两天里，我一直在做一些研究，以找到解决问题的方法，但无济于事。
我创建了一个 WCF 服务，如下所示：
[OperationContract]
void CopyMemberFile(string memberNumber, string fileName, byte[] fileBytes);
我从我的客户那里调用它，就像从 page_load 事件中一样：
byte[] filebytes = null;
using (Stream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
{
filebytes = new byte[fs.Length];
fs.Read(filebytes, (int)0, (int)fs.Length);
}
client.CopyMemberFile(memberNumber, Path.GetFileName(file), filebytes);
我的配置是这样的：

我得到的错误是：

我只能上传几个 KB 的文件，但任何大于 8KB 的文件都会失败
任何帮助都会很棒。
调用代码：
protected void Page_Load(object sender, EventArgs e)
{
var file = Request.Form["name"];
var memberNumber = Request.Form["memberNumber"];
var tempId = Guid.NewGuid();
var client = new MembershipApplicationsServiceReference.MembershipApplicationsClient();
client.LogEvent("Entered Upload.aspx");
try
{
byte[] filebytes = null;
using (Stream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
{
filebytes = new byte[fs.Length];
fs.Read(filebytes, (int)0, (int)fs.Length);
client.LogEvent("Starting service call from Upload.aspx");
client.CopyMemberFile(memberNumber, Path.GetFileName(file), filebytes);
}
client.LogEvent("Completed service call from Upload.aspx");
}
catch (Exception ex)
{
Debug.WriteLine(ex.StackTrace);
client.LogEvent("Upload.aspx Error: " + ex.Message + ex.StackTrace);
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
finally
{
client.LogEvent("Finishing up");
}
}
