The maximum string content length quota (8192) has been exceeded while reading XML data
提问by Tim
I'm trying to pass a large string (24,000 to 50,000 characters) to a self-hosted TCP WCF service.
我正在尝试将一个大字符串（24,000 到 50,000 个字符）传递给自托管 TCP WCF 服务。
I've upped the maxStringContentLength (everywhere) to 22008192.
我已将 maxStringContentLength（无处不在）提高到 22008192。
I read somewhere that I need to change the bindingConfiguration to "LargeBuffer" or "LongFields" but when I do this:
我在某处读到我需要将 bindingConfiguration 更改为“LargeBuffer”或“LongFields”，但是当我这样做时：
<endpoint address="" binding="netTcpBinding" bindingConfiguration="LongFields"
contract="ExStreamWCF.IService1">
or this:
或这个：
<endpoint address="" binding="netTcpBinding" bindingConfiguration="LargeBuffer"
contract="ExStreamWCF.IService1">
My service won't start. I really need this error to go away. Any ideas?
我的服务无法启动。我真的需要这个错误消失。有任何想法吗？
Thanks,
谢谢，

The bindingConfiguration needs to have the name you assign to the netTcpinding element - "LargeBuffer" or "LongFields" won't mean anything unless there is a binding element in the config file with that name. That is why your service won't start when you put that in - you most likely got a configuration error message of some sort, I bet.
bindingConfiguration 需要具有您分配给 netTcpinding 元素的名称 - “LargeBuffer”或“LongFields”将没有任何意义，除非配置文件中存在具有该名称的绑定元素。这就是为什么当你把它放进去时你的服务不会启动 - 你很可能会收到某种配置错误消息，我敢打赌。
To override the default 8192 setting for maxStringContentLength do this:
要覆盖 maxStringContentLength 的默认 8192 设置，请执行以下操作：
- Create a Binding element in the config file that has the size you want for maxStringContentLength and give it a name in the name attribute.
- In the endpoint element, assign the name from step 1 above to the attribute bindingConfiguration.
- 在配置文件中创建一个具有您想要的 maxStringContentLength 大小的 Binding 元素，并在 name 属性中为其指定一个名称。
- 在端点元素中，将上述步骤 1 中的名称分配给属性 bindingConfiguration。
If you don't specify a binding configuration for the endpoint, the service will use the default values.
如果您没有为端点指定绑定配置，服务将使用默认值。
For example, take your config file above. Under the tag, add the following binding configuration (note that your specific values and the optional attributes you use will vary depending on the needs of your service):
例如，以上面的配置文件为例。在标签下，添加如下绑定配置（注意你的具体值和你使用的可选属性会根据你服务的需求而有所不同）：
<bindings>
<netTcpBinding>
<binding name="ExStreamWCFBinding" closeTimeout="00:00:05" openTimeout="00:00:05" receiveTimeout="00:00:05" sendTimeout="00:00:05" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparison="StrongWildCard" maxBufferPoolSize="524288" maxBufferSize="524288" maxConnections="10" maxReceivedMessageSize="5242880">
<readerQuotas maxDepth="32" maxStringContentLength="5242880" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</binding>
</netTcpBinding>
</bindings>
Then when you define the endpoint:
然后当你定义端点时：
<endpoint address="" binding="netTcpBinding" bindingConfiguration="ExStreamWCFBinding" contract="ExStreamWCF.IService1">
EDITED TO ADD
编辑添加
Baed on your additional information, assing the bindingConfiguration attribute the value "NetTcpBinding_IService1" on the endpoint in your service.
根据您的附加信息，在您的服务端点上为 bindingConfiguration 属性分配值“NetTcpBinding_IService1”。

Sometimes changing "maxStringContentLength" value to maximum may not help.hence Add the below "default" binding inside the "basicHttpBinding" section in server config file.
有时将“maxStringContentLength”值更改为最大值可能无济于事。因此在服务器配置文件的“basicHttpBinding”部分中添加以下“默认”绑定。
<binding >
<readerQuotas maxDepth="32" maxStringContentLength="102400" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</binding>
