如何在C＃中更改窗体的颜色和大小？

// something like 
    Form1.BackColor = Color.Red; 
    From1.size = 1600,900; 

Answer 1

this.BackColor = Color.Red; 
this.Size = new Size(1600, 900); 

Answer 2

this.BackColor = System.Drawing.Color.Red 
this.Size = new Size(100, 100) 

Answer 3

如果您正在创建的窗体的实例：

Form1 form = new Form1(); 

form.BackColor = Color.Red; 
form.Size = new Size(1600,900); 

form.Show(); 

Answer 4

Form1.BackColor = Color.Red; 
Form1.Size = New System.Drawing.Size(1600, 900); 
Form1.Invalidate(); 

的Invalidate将导致形式重绘自己在什么范围
