Question

我需要帮助以解决错误（请参阅标题）所有帮助。我浏览了很多其他人的错误，但似乎没有人解决它，如果代码格式不正确，我很抱歉

public void button11_Click(object sender, EventArgs e)
{
    string weight = (ExtractNumbers(webBrowser1.Document.GetElementsByTagName("table")[2].GetElementsByTagName("td")[11].InnerText));
}

public void webBrowser3_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    string salesrate = (ExtractNumbers(this.webBrowser3.Document.GetElementsByTagName("table")[2].GetElementsByTagName("td")[17].InnerText)); 
}

public void timer9_Tick(object sender, EventArgs e)
{
    *if (weight >= salesrate)
    {
        i am getting this error with this IF statement
    }*
}

public static string salesrate(string expr)
{
    return string.Join(null, Regex.Split(expr, ""));
}

public static string weight(string expr)
{
    return string.Join(null, Regex.Split(expr, ""));
}

根据您发布的代码，以下是更改

string weight= "";
string salesrate = "";


public void button11_Click(object sender, EventArgs e)
{
    weight = (ExtractNumbers(webBrowser1.Document.GetElementsByTagName("table")[2].GetElementsByTagName("td")[11].InnerText));
}

public void webBrowser3_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    salesrate = (ExtractNumbers(this.webBrowser3.Document.GetElementsByTagName("table")[2].GetElementsByTagName("td")[17].InnerText)); 
}

public void timer9_Tick(object sender, EventArgs e)
{
    try {
      var parsedSalesRate = Double.parse(salesrate);
      var parsedWeight = Double.parse(weight);
      if(parsedWeight >= parsedSalesRate) {
          // ...
      }
    } catch(Exception ex) {
           throw;
    }
}



        public static string GetSalesrate(string expr)
        {
            return string.Join(null, Regex.Split(expr, ""));

        }
        public static string GetWeight(string expr)
        {
            return string.Join(null, Regex.Split(expr, ""));

        }
