Dear all,

I am working on a web application. I want to connect to the database available on remote location and fetch that information on the server side. I have one page at server side on which I can get that data on page load event. How can I get that data available on the remote location?

Any kind of link, suggestion and specially expert advice would be highly appreciated.

Thanks & Regards,

推荐答案

If the remote page is already displaying the data, you can examine the html content of the remote page. Now identify the html elements that are around the content.  For example, the records maybe contained in a <div> or <table> element.

With AJAX, you can download the html from this remote page. The next step will be to parse the html content to extract the data that you are looking for.

I hope it helps

您可能希望Web应用程序中的网页以XML格式写入数据:
创建一个新的WebForm

在Load事件中，输入以下代码:

You may want a webpage within your web application that writes the data in XML format :
Create a new WebForm

In the Load event put the following code :

string responseXml = CreateXmlFromDatabase();
Response.ContentType = "text/xml";
Response.Write(responseXml);
Response.End();

当然，还要创建一个函数CreateXmlFromDatabase()，该函数返回要作为字符串传递的数据:

And ofcourse create a function CreateXmlFromDatabase() which returns the data you want to pass as a string :

private string CreateXmlFromDatabase()
{
  StringBuilder sbXml = new StringBuilder("");
  sbXml.Append("<mydata>");

  // Add more XML here that contains data from your database

  sbXml.Append("</mydata>");
}
