您好我尝试了stackoverflow.com的所有解决方案，但它对我不起作用。
这是我的代码
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();
}
接口：
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "sendImage")]
void SendImage(byte[] img, string filename);
这是我的 Web.Config ：

答案 0 :(得分：2)
在WCF端（即与IIS分开），您没有使用在服务配置文件（Binding1）中定义的绑定：
<endpoint address="" binding="basicHttpBinding"
contract="WcfService1.IRestServiceImpl"
behaviorConfiguration="web">
指定要使用的绑定的类型，但由于您没有指定要使用的配置，因此您将获得basicHttpBinding的默认设置。要指定绑定配置，请使用bindingConfiguration属性，如下所示：
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="Binding1"
contract="WcfService1.IRestServiceImpl"
behaviorConfiguration="web">
可能有其他配置，但这是从 WCF 角度来看最常见的原因。
