HTTP:请求失败，HTTP状态为400:错误请求. [英] HTTP: The request failed with HTTP status 400: Bad Request.

问题描述

我想将字节数组传递给插入查询，但是我没有使用该参数.我直接将值传递给插入查询.
我收到以下错误:

Hi,

I want to pass the byte array into insert query but I am not using the parameter. I am directly passing values into insert query.
I am getting the following error:

at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)

from 
System.Web.Services
The request failed with HTTP status 400: Bad Request.

我的代码

my code

object str;
System.Text.UTF8Encoding enc = new System.Text.UTF8Encoding();
str = enc.GetString(image);

objGL.GetSelectByQuery("update empmast set photo=convert(varbinary(MAX),'" + str + "') where srno='" + txtSRNO.Text + "'");

非常感谢您的帮助.

Any help is greatly appreciated.
