当我尝试将图像作为byte[]发送时，WCF服务请求错误

这里我展示了通过WCF功能上传图片的全部功能。

每当我调用下面的服务，我得到不好的请求。请找出我写错的地方。

我的wcf服务:

http://XXX.XXX.X.XX/RestServiceImpl.svc/发送? canvasbyte = [B@40fa5860& EmployeeID = 1

My Service Interface:

    [OperationContract]
    [WebGet(
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "/send?canvasbyte={imgbyte}&EmployeeID={EmployeeID}")]
    string sendresponse(Byte[] imgbyte, string EmployeeID);

我的SVC

 public string sendresponse(Byte[] imgbyte, string EmployeeID)
    {
       db.GetExcuteNonQuery("update emp_tb_eob_Employee set Signature='" + imgbyte + "'      where EmployeeID=" + EmployeeID);
        return "Success";
    }
