form1 上面我放了个图片 然后又把按钮放在了图片上面 怎么让按钮只显示按钮里面的字

在按钮的属性里面找下，把边框、背景、阴影都去掉，就只剩下字了。
大体思路可以按照这个来

    btn.FlatStyle = FlatStyle.Flat;//样式
    btn.ForeColor = Color.Transparent;//前景
    btn.BackColor = Color.Transparent;//去背景
    btn.FlatAppearance.BorderSize = 0;//去边线
    btn.FlatAppearance.MouseOverBackColor = Color.Transparent;//鼠标经过
    btn.FlatAppearance.MouseDownBackColor = Color.Transparent;//鼠标按下

你可以把图片隐藏起来，有个属性Visible

不如直接用Label

你放个按钮，但又不想显示按钮，那你为什么要放按钮，为什么不放label，label也可以点击啊

已经解决了
private void Form1_Load(object sender, EventArgs e)
{
PictureBox pb = this.pictureBox1;
this.button1.FlatStyle = FlatStyle.Flat;
this.button1.BackColor = Color.Transparent;
this.button1.FlatAppearance.BorderSize = 0;
this.button1.Parent = pb;

}

也可以加上this.button1.FlatAppearance.MouseOverBackColor = Color.Transparent;
this.button1.FlatAppearance.MouseDownBackColor = Color.Transparent;
