c# adding dynamic button[^]


still got an error.

推荐答案

Button[,] cal = new Button[intnum, intnum];
Button b11 = cal[1, 1]; // b11 is null
Button newbtn = new Button(); // create new button 
newbtn.Text = "test";
cal[1, 1] = newbtn; //and assign it to 1, 1
this.Controls.Add(cal[1, 1]); // now you can see the button in UI

因为没有将控件添加到任何容器中.将其添加到表单中已定义的占位符面板中.给它一个出现的位置/位置.

更新:
您尚未创建按钮.首先创建它们，然后将其添加到容器中以进行显示.

Because you did not add the control to any container. Add it to a defined placeholder, panel in your form. Give it a place/location to appear.

UPDATE:
You have not created buttons. Create them first and then add it to the container for display.
