title: how to convert char @"\" to Escape String \ by C#
body: <p>I have grabbed some data from a website.<strong>A string which is named as urlresult in the data</strong> is <code>"http:\/\/www.cnopyright.com.cn\/index.php?com=com_noticeQuery&amp;method=wareList&amp;optionid=1221&amp;obligee=\u5317\u4eac\u6c83\u534e\u521b\u65b0\u79d1\u6280\u6709\u9650\u516c\u53f8&amp;softwareType=1"</code>.</p>
  
  <p>what I want to do is to get rid of the first three char @'\' in the string <strong>urlresult</strong>  above . I have tried the function below:</p>
  
  <pre><code>public string ConvertDataToUrl(string urlresult )
  {
  
     var url= urlresult.Split('?')[0].Replace(@"\", "") + "?" + urlresult .Split('?')[1];
  
  
    return url
  
  }
  </code></pre>
  
  <p>It returns <code>"http://www.cnopyright.com.cn/index.php?com=com_noticeQuery&amp;method=wareList&amp;optionid=1221&amp;obligee=\\u5317\\u4eac\\u6c83\\u534e\\u521b\\u65b0\\u79d1\\u6280\\u6709\\u9650\\u516c\\u53f8&amp;softwareType=1"</code> which is incorrect.</p>
  
  <p>The correct result is  <code>"http://www.cnopyright.com.cn/index.php?com=com_noticeQuery&amp;method=wareList&amp;optionid=1221&amp;obligee=北京沃华创新科技有限公司&amp;softwareType=1"</code> </p>
  
  <p>I have tried many ways,but it hasn't worked.I have no idea how to get the correct result.</p>
