c# - 获取点击的图片框数组索引

Question

我正在动态创建一些图片框并为图片框点击事件如下

Image myImage = Image.FromFile("image/Untitled6.png"); 
PictureBox[] txtTeamNames = new PictureBox[5];        

for (int i = 0; i < txtTeamNames.Length; i++)
{
  var txt = new PictureBox();
  txtTeamNames[i] = txt;                
  txtTeamNames[i].Image = myImage;                
  txtTeamNames[i].Height = 53;
  txtTeamNames[i].Width = 48;                
  this.panel1.Controls.Add(txtTeamNames[i]);                
  txtTeamNames[i].Visible = true;
  txtTeamNames[i].Click += new EventHandler(this.clcikeventhandle);
}

当有人点击任何图片框时，我如何找到它的数组索引和名称？

void clickEventHandler(object sender, EventArgs e)
{          
  //???
}

Answer 1

您可以通过sender 参数访问PictureBox。所以试试这个:

PictureBox[] txtTeamNames;

void YourMethod()
{
    Image myImage = Image.FromFile("image/Untitled6.png"); 
    txtTeamNames = new PictureBox[5];        
    //The same as your code
}   

void clcikeventhandle(object sender, EventArgs e)
{          
    int index = txtTeamNames.IndexOf(sender As PictureBox);
}

编辑:方法 #2

但是如果您不喜欢在类范围内声明该数组，您可以尝试这种方法:

//Same as your code
for (int i = 0; i < txtTeamNames.Length; i++)
{
    //Save as your code
    txtTeamNames[i].Tag = i;                        // ADD THIS LINE
}

然后:

void clcikeventhandle(object sender, EventArgs e)
{            
    int index = int.Parse((sender as PictureBox).Tag.ToString());
}
