Question

首先，我想说我对编码很新，虽然几年前我已经学会了一些基础知识。

现在我正在尝试制作一个搜索用户输入文本的程序。并替换其中的一些部分，然后返回新文本。

像这样：

stormcloud-146919.appspot.com/purchase/listing/?global=ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ckULEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDAsSDEl0ZW1JbnN0YW5jZRiAgICAgOSRCgw&coin= 3 ＆安培; xpPlayer = 10 ＆安培; sidekick1 = ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ckULEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDAsSDEl0ZW1JbnN0YW5jZRiAgICAkMmPCgw＆安培; xpSidekick1 =的 10 ＆安培; sidekick2 = ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ckULEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDAsSDEl0ZW1JbnN0YW5jZRiAgICA0OqZCgw＆安培; xpSidekick2 = 10 ＆安培; K = ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ciwLEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDA＆安培; L =＆ahNzfnN0b3JtY2xvdWQtMTQ2OTE5chQLEgdMaXN0aW5nGICAgID00JwKDA放大器;

搜索粗体部分并替换为我的自定义文本或数字。

我希望您希望更新一些查询字符串参数值。您可以使用HttpUtility.ParseQueryString()。找到下面的示例。

var url = "stormcloud-146919.appspot.com/purchase/listing/?global=ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ckULEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDAsSDEl0ZW1JbnN0YW5jZRiAgICAgOSRCgw&coin=3&xpPlayer=10&sidekick1=ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ckULEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDAsSDEl0ZW1JbnN0YW5jZRiAgICAkMmPCgw&xpSidekick1=10&sidekick2=ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ckULEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDAsSDEl0ZW1JbnN0YW5jZRiAgICA0OqZCgw&xpSidekick2=10&k=ahNzfnN0b3JtY2xvdWQtMTQ2OTE5ciwLEgNVSUQiEDEyNTA0NjQ5MDgzMjUyNDIMCxIGUGxheWVyGICAgICAgIAKDA&l=ahNzfnN0b3JtY2xvdWQtMTQ2OTE5chQLEgdMaXN0aW5nGICAgID00JwKDA&";
Console.WriteLine(url);
var uriBuilder = new UriBuilder(url);
var query = HttpUtility.ParseQueryString(uriBuilder.Query);
query["coin"] = "4";
query["xpPlayer"] = "4";
query["xpSidekick1"] = "4";
query["xpSidekick2"] = "4";

uriBuilder.Query = query.ToString();
Console.WriteLine(uriBuilder.ToString());

看看它是否符合您的要求。记得导入System.Web命名空间。

using System.Web;

你可以使用 string [] split = input.Split（new Char [] {'＆amp;'}）; 并为每个分裂.Split（新Char [] {'='}）; 替换所需的值并将所有部分连接到新字符串。

编辑并查找querystring参数值
