推荐答案

首先在您的项目中添加通用处理程序.

通用处理程序是实现System.Web.IHttpHandler接口的.NET组件.任何实现IHttpHandler接口的类都可以充当传入HTTP请求的目标.页面也是通用处理程序.通常，通用处理程序具有ASHX的扩展名.
然后，在处理程序中编写一个函数，您可以在其中指定要提交的内容.喜欢

//示例
私有无效CheckRequisitionNo()
{
字符串refSourceString = String.Empty;
字符串RN = HttpContext.Current.Request.QueryString ["rn"];

//根据您的要求编写代码
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType =文本/纯文本";
HttpContext.Current.Response.Write(refSourceString);
HttpContext.Current.Response.Flush();
}

然后，从客户端调用该函数.

喜欢:
DataHandler.ashx?CallMode = CheckRequisitionNo&ItemCode =''+

At first add a Generic handler in your project.

Generic handlers are the .NET components that implement the System.Web.IHttpHandler interface. Any class that implements the IHttpHandler interface can act as a target for the incoming HTTP requests. Page is also generic handler. In general generic handlers have an extension of ASHX.

Then, In the handler write a function in which you specify what do you want do on submit. like

//Example
private void CheckRequisitionNo()
{
String refSourceString = String.Empty;
String RN = HttpContext.Current.Request.QueryString["rn"];

//Write the code as per your requirements
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "text/plain";
HttpContext.Current.Response.Write(refSourceString);
HttpContext.Current.Response.Flush();
}

Then , call the function from client side.

Like:
DataHandler.ashx?CallMode=CheckRequisitionNo&ItemCode='' +
