如何添加（追加）一个单词到同一个句子，每个单词使用一个按钮（单击）

我非常感谢任何帮助。我有20多个按钮，每个按钮都有一个词，或者一个空格或句点。每次我点击一个按钮时，预先存在的单词将被删除并替换为新单词。我需要每个单词和/或空间留在原地，直到我点击“清除”按钮。如何添加（追加）一个单词到同一个句子，每个单词使用一个按钮（单击）

也许这是以前在不同的搜索条件下提出的问题？我倾向于认为我需要确定一个字符串变量，但不知道如何开始。

使用lb1SentenceText.Text+=whatever.Text;。

+ =相当于lbSentence.Text = lblSentenceText.Text + whatever.Text。

基本上，它将右侧string附加或连接到左侧的string。希望它是有道理的？

所以：

string rhs="Hello " ; 
string lhs = "World"; 
string rhs = rhs + lhs;//Hello World

点击按钮的事件，将其更改为+=，而不是=（除清除按钮）。这相当于写作something = something + newValue;。

哇！像+ =这么简单？ ..但对我来说似乎如此困难。非常感谢。我确信所有这些反应都是有道理的，我会在接下来的几天里对它们进行研究。我整天搜索使用这么多搜索词组合，但没有像这样！我刚刚开始使用C＃，因此将努力尽量减少代码，因为我学习。我开始想象我肯定需要引入一个字符串变量，但不是。谢谢！谢谢！ – 2013-02-12 22:11:28

请大家鼓舞。你有一个多余的代码。

btnA.Click += AppendButtonText; 
    btn_a.Click += AppendButtonText; 
    ... 


    private void AppendButtonText(object sender, EventArgs e) 
    { 
     var button = sender as Button; 
     if (button != null) 
     { 
      lblSentenceText.Text += button.Text; 
     } 
    }

是的，我被告知“现在不用担心太多的代码......只是学习过程......”参加我的第一个C＃课程。非常感谢！ – 2013-02-12 22:17:25

尝试：

lb1SentenceText.Text = lb1SentenceText.Text + *something*.text

+ =操作符是指添加到，和经修饰的可变等于加入（中间体，字符串）附加到原始值（X = 1; X + = 3; X是现在4）

尝试这种情况：

button.Click += new System.EventHandler(ButtonClick); 
button1.Click += new System.EventHandler(ButtonClick); 
// And for each button, one of those. 
private void ButtonClick(object sender, System.EventArgs e) 
{ 
// Do whatever you want to do here, you can place the TEXT to be appended on the button, if so: 
lb1SentenceText.Text += sender.Text; 
}

//Simple.Create a global variable and within each button click event do this; 

string yourStrVar = ""; //Must be global 

yourStrVar+= ((Button)sender).Text
