推荐答案

请按照以下三个步骤设置透明颜色.

步骤1:找到您的控件类的构造函数.

步骤2:在构造函数中，调用表单的SetStyle方法.这将使您的控件支持透明的背景色.

Follow three steps process to set the transparent color.

Step 1: Locate the constructor for your control class.

Step 2: In the constructor, call the SetStyle method of your form. This will enable your control to support a transparent backcolor.

SetStyle(ControlStyles.SupportsTransparentBackColor, true);

步骤3:在上一步中添加的代码行之后，将控件的BackColor设置为Transparent.

Step 3: After the line of code you added in the previous step, set your control''s BackColor to Transparent.

this.BackColor = Color.Transparent;

执行此操作，

将PictureBox的背景色设置为与其所在窗体的背景色相同.

例如.如果

Do This,

Set the backcolor of PictureBox to be same as the backcolor of the form on which it is.

Eg. if

this.BackColor= Color.Blue;
pictureBox1.BackColor = Color.Blue;

也可以尝试对其他具有真实透明度的图像进行一次处理.也许您的图片没有透明度！

Also try doing it once with some other image which has true transparency. Maybe your image does not have transparency!!
