我收到错误

尝试发出请求时发生Web异常。远程服务器返回错误：（413）请求实体太大。：

尝试从ASP.Net Web应用程序上传文件到Sharepoint站点时。用户添加通过ASP.Net文件上载控件选择文件，下面的代码将其上传到Sharepoint。我试图上传的文件大约是250k（即不是很大）。

代码如下：

public string SharepointWebClientSOAPPost(Uri webService, string SOAPAction, string contentType, string postData, NetworkCredential networkCredential = null, string webProxy = "", NetworkCredential webserviceCredentials = null)
{
    try
    {
        using (WebClient client = new WebClient())
        {
            if (string.IsNullOrEmpty(webProxy) && webserviceCredentials != null)
            {
                client.Proxy = new WebProxy(new Uri(webProxy));
                client.Proxy.Credentials = webserviceCredentials;
            }
            if (networkCredential != null)
            {
               client.Credentials = networkCredential;
            }

            client.Headers.Add(HttpRequestHeader.ContentType, contentType);
            client.Headers.Add("SOAPAction", SOAPAction);

            // Apply ASCII Encoding to obtain the string as a byte array.
            var byteArray = Encoding.ASCII.GetBytes(postData);

            // Upload the input string using the HTTP 1.0 POST method.
            var responseArray = client.UploadData(webService, "POST", byteArray);

            // Decode and return the response.
            var response = Encoding.ASCII.GetString(responseArray);
            return response; 
        }
    }
    catch(Exception ex)
    {
        //etc.
    }
}

我在web.config中有以下设置

<httpRuntime maxRequestLength="1024000" />

如果我使用几k的文本文件，它工作正常，所以我认为基本的想法是正确的（SOAP消息格式正确，URL正确）。但是，运行SP站点的人告诉我，它被配置为接受最大50MB的文档。

我可以开始寻找问题的任何想法吗？

您的代码使用WCF上传文件而不是ASP.NET，您必须像这样配置web.config maxReceivedMessageSize ：

<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding maxReceivedMessageSize="10485760">

      </binding>
    </basicHttpBinding>
  </bindings>  
</system.serviceModel>

将文件上传到Sharepoint返回413请求实体太大
