C＃如何點擊一個按鈕啓動計數器，然後重新啓動並在另一個按鈕上單擊增加相同的計數器？

Question

在button3_click我需要我的計數器開始從0

 static int btncntr=0; 
     private void button2_Click(object sender, EventArgs e) 
    { 
     btncntr++; 
     timer1.Stop(); 
     timer1.Start(); 
     string a = GetLetter(2); 
     char b = char.Parse(a); 
     SetLetter(b); 
    } 
     private void button3_Click(object sender, EventArgs e) 
    { 
      btncntr++; 
      timer1.Stop(); 
      timer1.Start(); 
      string a = GetLetter(3); 
      char b = char.Parse(a); 
      SetLetter(b); 
    } 

我試圖模擬短信打字計數。在button2上有ABC，在按鈕3上有DEF。如果我點擊一次button2我應該得到A，雙擊給我B等 如果我點擊一次button2和一次button3我得到的是AE而不是AD。每個按鈕都有計數器會很複雜，我更喜歡這種方式。謝謝。 :)

這應該這樣做....

static int btncntr=0; 
static int lastButton=0; 

private void button2_Click(object sender, EventArgs e) 
{ 
    //if the last click wasnt button 2 then reset 
    if(lastButton != 2) 
     btncntr = 0; 

    //save last button clicked 
    lastButton = 2; 

    btncntr++; 
    timer1.Stop(); 
    timer1.Start(); 
    string a = GetLetter(2); 
    char b = char.Parse(a); 
    SetLetter(b); 
} 

private void button3_Click(object sender, EventArgs e) 
{ 
    //if the last click wasnt button 3 then reset 
    if(lastButton != 3) 
     btncntr = 0; 

    //save last button clicked 
    lastButton = 3; 

    btncntr++; 
    timer1.Stop(); 
    timer1.Start(); 
    string a = GetLetter(3); 
    char b = char.Parse(a); 
    SetLetter(b); 
}

SetLetter後，您需要重置計數器，

SetLetter(b); 
btncntr=0;
