C# 当我尝试以字节[]形式发送图像时，WCF服务请求错误

这里我展示了通过WCF函数上传图像的全部功能

每当我呼叫下面的服务时，我都会收到错误的请求。请找出我犯的错误

我的wcf服务：

我的服务界面：

    [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";
    }

< /代码> 您可以考虑将图像传递为<代码> Base64 < /代码>编码<代码>字符串< /代码>或<代码>流< /代码> .<
下面的链接很好地概括了这些选项：

您的服务方法似乎公开了SQL注入目标…我试图以流的形式发送图像。但我有以下错误，我试图发送我的图像作为流。但是我得到了以下错误“type'System.IO.Stream”，但是类型'System.IO.Stream'不能由'QueryStringConverter'转换。UriTemplate查询值的变量必须具有可以由'QueryStringConverter'转换的类型。我尝试以base64string的形式发送，但得到了404错误。实际上我需要通过url发送图像。
