我已在我的代码中启用了流媒体,但仍需要很长时间才能上传大文件。以下是发生的事情:

我的WPF代码调用服务来上传文件,但很长一段时间后服务器上的调试器被命中。对于10 MB文件,大约需要1.07分钟。

以下是代码:

致电代码:

using (System.IO.FileStream stream = new System.IO.FileStream(fileInfo.FullName, System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {
                uploadRequestInfo.FileName = fileInfo.Name;
                uploadRequestInfo.Length = fileInfo.Length;
                uploadRequestInfo.FileByteStream = stream;
                clientUpload.UploadFile(uploadRequestInfo);
            }

运营合同:

public partial class RemoteFileInfo {

        [System.ServiceModel.MessageHeaderAttribute(Namespace="http://tempuri.org/")]
        public string FileName;

        [System.ServiceModel.MessageHeaderAttribute(Namespace="http://tempuri.org/")]
        public long Length;

        [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://tempuri.org/", Order=0)]
        public System.IO.Stream FileByteStream;

        public RemoteFileInfo() {
        }

        public RemoteFileInfo(string FileName, long Length, System.IO.Stream FileByteStream) {
            this.FileName = FileName;
            this.Length = Length;
            this.FileByteStream = FileByteStream;
        }
    }

app.config:

        <binding name="BasicHttpBinding_ITransferService" closeTimeout="00:10:00"
          openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
          messageEncoding="Text" textEncoding="utf-8" transferMode="Streamed"
          useDefaultWebProxy="true">
            <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
              maxBytesPerRead="4096" maxNameTableCharCount="16384" />
            <security mode="None">
                <transport clientCredentialType="None" proxyCredentialType="None"
                  realm="" />
                <message clientCredentialType="UserName" algorithmSuite="Default" />
            </security>
        </binding>

您可以通过编辑承载WCF服务的Web应用程序的Web.config来在服务合同级别对其进行优化。

为了指出正确的方向,我必须知道有关应用程序托管的Web服务的更多信息,等等。但是,这将是构建自定义绑定的方法:

  • TCP传输
  • 二进制编码
