我在通过Web服务发送一个大文件时遇到问题（系统.Web.服务.协议.SoapHttpClientProtocol.ReadResponse）。
当文件小于20 MB时，一切正常，如果文件大于20 MB，我会得到404代码的响应。

例外信息

Exception Type: System.Net.WebException
Status: ProtocolError
Response: System.Net.HttpWebResponse
Message: The request failed with HTTP status 404: Not Found.
Data: System.Collections.ListDictionaryInternal
TargetSite: System.Object[] ReadResponse(System.Web.Services.Protocols.SoapClientMessage, System.Net.WebResponse, System.IO.Stream, Boolean)
HelpLink: NULL
Source: System.Web.Services

您的档案上传似乎已逾时：

您可以在global.asax中捕获此错误，以查看是否存在以下情况：

Protected Sub Application_EndRequest(ByVal sender As Object, ByVal e As System.EventArgs)

    Dim context As HttpContext = HttpContext.Current.ApplicationInstance.Context
    If Not IsNothing(context) Then

        If Not context.Response.StatusCode = HttpStatusCode.OK Then

            'Detect file upload exceeded max length:
            If context.Response.StatusCode = 404 And
                context.Response.SubStatusCode = 13 Then
                'clear the previous error page content:
                context.Response.Clear()
                'redirect to custom error page:
                context.Server.Transfer("~/error.aspx?code=404.13", False)
            End If

        End If

    End If
End Sub

您也可以在web.config中增加请求长度，如下所示：

<system.web>
    <httpRuntime maxRequestLength="29296" />
</system.web>

如果Web应用程序中存在Web服务引用，则只需删除该Web服务引用，然后重新生成，运行该Web服务，然后再次将该Web服务引用添加到Web应用程序中。
