WCF文件上载大文件,wcf,Wcf,在过去的两天里，我一直在做一些研究，以找到解决我问题的方法，但都没有用 我创建了一个WCF服务，如下所示： [OperationContract] void CopyMemberFile(string memberNumber, string fileName, byte[] fileBytes); 我从客户端调用它，就像从页面加载事件调用它一样： byte[] filebytes = null; using (Stream fs = new FileStream(file, FileMod

在过去的两天里，我一直在做一些研究，以找到解决我问题的方法，但都没有用

我创建了一个WCF服务，如下所示：

[OperationContract]
void CopyMemberFile(string memberNumber, string fileName, byte[] fileBytes);
我从客户端调用它，就像从页面加载事件调用它一样：

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);
我的配置如下：

客户端配置：

我只能上传几个KB的文件，但任何超过8KB的文件都会失败

任何帮助都会很棒

呼叫代码：

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");
    }
}
查看服务的配置文件，您使用的是.NET 4.0，没有指定任何绑定，因此您将收到
basicHttpBinding
的默认设置。如上面评论中所建议的，按如下方式更新服务的配置文件：

这将告诉WCF将您的设置用于
basicHttpBinding
，而不是.NET默认设置

或者，您可以省略绑定定义上的
name
属性，WCF将使用它作为配置文件处理的所有服务的默认绑定（如果您有多个）

如果这没有帮助，或者如果您现在遇到了不同的错误，请告诉我们，我们将从中解决。

消息是-格式化程序在尝试反序列化消息时引发了异常：反序列化操作“CopyMemberFile”的请求消息体时出错。读取XML数据时已超过最大数组长度配额（16384）。可以通过更改创建XML读取器时使用的XmlDictionaryReaderQuotas对象的MaxArrayLength属性来增加此配额。第1行，位置45385。您可以发布您的服务和客户端配置文件的完整服务模型部分吗？听起来您的客户机使用的是默认限制（几K）。此外，您可能希望查看大文件的WCF流。请在问题中通过您的客户端web.config-代码和XML在注释中显示不好：）刚刚添加，需要一些时间才能使用。您的第一句话提示我，我缺少服务器端配置，因此默认为标准配置？
