从字符串c#中删除单词

Question

我正在开发一个ASP.NET 4.0 Web应用程序,它要做的主要目标是转到MyURL变量中的URL 然后从上到下读取它,搜索以"description"开头的所有行,并且只保留那些删除所有HTML标记.我接下来要做的是从结果后面删除"描述"文本,所以我只剩下我的设备名称.我该怎么做？

protected void parseButton_Click(object sender, EventArgs e)
    {
        MyURL = deviceCombo.Text;
        WebRequest objRequest = HttpWebRequest.Create(MyURL);
        objRequest.Credentials = CredentialCache.DefaultCredentials;
        using (StreamReader objReader = new StreamReader(objRequest.GetResponse().GetResponseStream()))
        {
            originalText.Text = objReader.ReadToEnd();
        }

        //Read all lines of file
        String[] crString = { "<BR>&nbsp;" };
        String[] aLines = originalText.Text.Split(crString, StringSplitOptions.RemoveEmptyEntries);

        String noHtml = String.Empty;

        for (int x = 0; x < aLines.Length; x++)
        {
            if (aLines[x].Contains(filterCombo.SelectedValue))
            {
                noHtml += (RemoveHTML(aLines[x]) + "\r\n");

            }
        }
        //Print results to textbox
        resultsBox.Text = String.Join(Environment.NewLine, noHtml);
    }
    public static string RemoveHTML(string text)
    {
        text = text.Replace("&nbsp;", " ").Replace("<br>", "\n");
        var oRegEx = new System.Text.RegularExpressions.Regex("<[^>]+>");
        return oRegEx.Replace(text, string.Empty);
    }

Answer 1

好的,所以我想出了如何通过我现有的一个功能删除单词:

public static string RemoveHTML(string text)
{
    text = text.Replace("&nbsp;", " ").Replace("<br>", "\n").Replace("description", "").Replace("INFRA:CORE:", "")
        .Replace("RESERVED", "")
        .Replace(":", "")
        .Replace(";", "")
        .Replace("-0/3/0", "");
        var oRegEx = new System.Text.RegularExpressions.Regex("<[^>]+>");
        return oRegEx.Replace(text, string.Empty);
}

Answer 2

public static void Main(String[] args)
{
    string str = "He is driving a red car.";

    Console.WriteLine(str.Replace("red", "").Replace("  ", " "));
}   

输出：他正在开车。

注意：在第二个替换它的双空格。
