错误1运算符'> ='不能应用于'方法组'和'方法组'类型的操作数

Question

我需要错误帮助（请参阅标题）以获得所有帮助。我已经通过其他人的错误，但没有很多网页浏览都似乎解决它，也对不起，如果根据您发布的代码的代码不正确

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，这里有变化

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, "")); 

     }
