Wcf服务没有获取大量数据（文本） [英] Wcf service not taking huge data(text)

问题描述

我有客户端A和客户端B.他们通过WCF服务进行通信。



我正在尝试发送大量文本（15000个字符），但WCF服务不是获取此数据。



但是当我发送8100个字符的文本时，WCF服务获取数据并发送给客户B.



请告诉我如何解决这个问题...



以下是我的Web.config：

CLient A代码（按钮点击代码，我发送数据）

 DataMessage message =  new  DataMessage（）; 
 message.Age =& quot; 
  string  Xml = _DataResult; 
 message.Name = Xml.ToString（）; 

客户B代码（文本框从WCF服务获取结果）

  this  .label1.Text = eventData.Age; 
  this  .textBox1.Text = eventData.Name; 

WCF中的DataMember：

 [DataMember] 
  public  字符串名称{获取;  set ; } 
 [DataMember] 
  public   string 年龄{获得;  set ; } 

我尝试过：



请建议我如何解决这个问题

解决方案

欢迎来到wcf世界....这就是为什么我不再使用它，因为你有这么多当你不知道你会收到什么的大小时，你会惊喜地生产......



看看装订中的选项，

你有maxReceivedMessageSize，maxBufferSize，maxBufferPoolSize，readerQuotas来设置，

这里有一个例子：

  <   basichttpbinding  >  
 <   binding     name   =  basicHttp    allowcookies   =  true  >  
 maxReceivedMessageSize =10000000
 maxBufferSize =10000000
 maxBufferPoolSize =10000000
 <   readerquotas     maxdepth   =  32 >  
 maxArrayLength =100000000
 maxStringContentLength =100000000
 <   / readerquotas  < span class =code-keyword>>  <   / binding  >  
 <   / basichttpbinding  >  
 

At service section使用wsDualHttpBinding将 bindingConfiguration 元素添加到您的终端：

 <   endpoint    地址  =     binding   =  wsDualHttpBinding    bindingconfiguration   =  myBindingConfig    contract   =  WcfServ iceLibrary.IMyService    /  >  

到的根目录system.serviceModel 部分添加绑定包含如下配置的部分：

 <  绑定 >  
 <   wsDualHttpBinding  >  
 <   binding     name   =  myBindingConfig    maxReceivedMessageSize   =  25000    /  >  
 <   / wsDualHttpBinding  >  
 <   / bindings  >  

I have Client A and Client B. They communicate through WCF Service.

I am trying to send huge text(15000 characters), but WCF Service is not getting this data.

But when I send 8100 characters of text, WCF Service gets the data, and send to client B.

Please tell me how to solve this issue...

below is my Web.config:

<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />

    <directoryBrowse enabled="true"/>
  </system.webServer>

</configuration>

CLient A code(Button click code where I am sending Data)

DataMessage message = new DataMessage();
                message.Age = "
                string Xml = _DataResult;
                message.Name = Xml.ToString();

Client B code(Where textbox gets the result from WCF Service)

this.label1.Text = eventData.Age;
            this.textBox1.Text = eventData.Name;

DataMember in WCF:

[DataMember]
        public string Name { get; set; }
[DataMember]
        public string Age { get; set; }

Please suggest me how to solve this Issue

Welcome in the wcf world.... that's why i don t use it anymore, because you have so much surprise in production when you don t know the size of what you will receive...

look in option in the binding ,
you have maxReceivedMessageSize,maxBufferSize,maxBufferPoolSize,readerQuotas to set,
here is an example :

<basichttpbinding>
    <binding name="basicHttp" allowcookies="true">
             maxReceivedMessageSize="10000000"
             maxBufferSize="10000000"
             maxBufferPoolSize="10000000"
        <readerquotas maxdepth="32">
             maxArrayLength="100000000"
             maxStringContentLength="100000000"
    </readerquotas></binding>
</basichttpbinding>

At service section add bindingConfiguration element to your endpoint with wsDualHttpBinding:

<endpoint address="" binding="wsDualHttpBinding" bindingconfiguration="myBindingConfig" contract="WcfServiceLibrary.IMyService" />

To root of system.serviceModel section add bindings section with configuration like this:

<bindings>
    <wsDualHttpBinding>
        <binding name="myBindingConfig" maxReceivedMessageSize="25000" />
    </wsDualHttpBinding>
</bindings>
