A3-輸出入介面

TextBox.ForeColor = Color.Red;

richTextBox1.SelectionFont = new Font("Arial", 12);

richTextBox1.SelectionColor = Color.Purple;

1.讀取檔案至image類別

Image myPic = Image.FromFile(@"C:\Documents and Settings\ggyy\My Documents\1.PNG");

2.顯示圖片至pictureBox1

this.pictureBox1.BackgroundImage = myPic;

上述動作只要將Image換成Bitmap，一樣可以完成相同功能。

Bitmap myBit = new Bitmap(@"C:\Documents and Settings\ggyy\My Documents\1.PNG");

如何在控件背景顯示圖片

OK==>pictureBox1.BackgroundImage= Image.FromFile(@"D:\123.jpg");
