錯誤1運算符'> ='不能應用於'方法組'和'方法組'類型的操作數

Question

我需要錯誤幫助（請參閱標題）以獲得所有幫助。我已經通過其他人的錯誤，但沒有很多網頁瀏覽都似乎解決它，也對不起，如果根據您發佈的代碼的代碼不正確

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, "")); 
}

格式化，這裏有變化

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, "")); 

     }
