如何获取页面的来源

Question

如何使用 java、c# 或任何其他网络语言获取 google、wikipedia 或任何其他页面的来源。另外，我如何使用 ajax 从互联网加载谷歌或任何其他网站。我试过了：

function ajaxFunction(){
    var ajaxRequest; // The variable that makes Ajax possible!
    try{
        // Opera 8.0+, Firefox, Safari
        ajaxRequest = new XMLHttpRequest();
    } catch (e){
        // Internet Explorer Browsers
        try{
            ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try{
                ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e){
                // Something went wrong
                alert("Your browser broke!");
                return false;
            }
        }
    }

    // Create a function that will receive data
    // sent from the server and will update
    // div section in the same page.
    ajaxRequest.onreadystatechange = function(){
        if(ajaxRequest.readyState == 4){
            var ajaxDisplay = document.getElementById('23');
            ajaxDisplay.innerHTML = ajaxRequest.responseText;
        }
    }
    // Now get the value from user and pass it to
    // server script.
    ajaxRequest.open("POST", "https://www.google.com/search", true);
    ajaxRequest.send(null);
}

您可以使用 HttpRequest 和 HttpResponse ，如果您需要代码来获取给定 URL 的页面内容，请告诉我
