Question

我有这个按钮，在代码中创建，具有背景图像并且是透明的。到目前为止这么好，它的工作原理，可怕的灰色背景颜色消失了。除了当我将鼠标悬停在它上面时，刺激性不断回来。

所以我尝试了我能想到的，并且添加了一个eventlistener，它可以在MouseHover，Enter和Leave上将背景颜色更改为透明。但似乎没有任何效果。

有什么想法吗？

到目前为止，这是我的代码：

    private void CreateFirstScreen() {
        mainForm.BackgroundImage = Image.FromFile(@"[img dir]");

        Button nextBtn = new Button();
        nextBtn.BackColor = Color.Transparent;        <== this works!
        nextBtn.BackgroundImage = Image.FromFile(@"[img dir]");
        nextBtn.FlatStyle = FlatStyle.Flat;

        nextBtn.FlatAppearance.BorderSize = 0;
        nextBtn.SetBounds(1555, 820, 274, 106);

        mainForm.Controls.Add(nextBtn);


        nextBtn.MouseHover += (sender, args) => {
            nextBtn.BackColor = Color.Transparent;    <= doesn't work
        };
        nextBtn.MouseEnter += (sender, args) => {
            nextBtn.BackColor = Color.Transparent;    <= doesn't work
        };
        nextBtn.MouseLeave += (sender, args) => {
            nextBtn.BackColor = Color.Transparent;    <= doesn't work
        };
        nextBtn.Click += (sender, args) => {
            CreateSecondScreen();                     <= does work
            mainForm.Controls.Remove(nextBtn);        <= does work
        };
    }

尝试添加此内容：

nextBtn.FlatAppearance.MouseOverBackColor=Color.Transparent;

鼠标悬停上的C＃按钮透明背景
