Sending byte array to WCF Service
提问by ?ukasz Golec
Hello I tried all solutions from stackoverflow.com but it didn't work for me.
您好，我尝试了来自 stackoverflow.com 的所有解决方案，但对我不起作用。
Here is my code
这是我的代码
WCF Service:
WCF 服务:
public void SendImage(byte[] img, string filename)
{
MemoryStream memoryStream = new MemoryStream(img);
FileStream stream = new FileStream(AppDomain.CurrentDomain.BaseDirectory + filename, FileMode.Create);
memoryStream.CopyTo(stream);
stream.Close();
}
Interface:
界面：
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "sendImage")]
void SendImage(byte[] img, string filename);

On the WCF end (i.e., separate from IIS), you're not using the binding you defined in the service config file (Binding1):
在 WCF 端（即与 IIS 分开），您没有使用您在服务配置文件 ( Binding1) 中定义的绑定：
<endpoint address="" binding="basicHttpBinding"
contract="WcfService1.IRestServiceImpl"
behaviorConfiguration="web">
You specify the typeof binding to use, but since you didn't specify the configuration to use, you will get the default settings for basicHttpBinding. To specify the binding configuration, use the bindingConfigurationattribute, like this:
您指定要使用的绑定类型，但由于您没有指定要使用的配置，您将获得basicHttpBinding. 要指定绑定配置，请使用该bindingConfiguration属性，如下所示：
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="Binding1"
contract="WcfService1.IRestServiceImpl"
behaviorConfiguration="web">
There could be other configurations to, but this is the most common reason from a WCFperspective.
可能还有其他配置，但从WCF 的角度来看，这是最常见的原因。
