记住上面还有一句在写在dispose()方法里.就是SaveSettings()方法.
书上抄的原码:为什么再次启动Form的位置不能固定啊!颜色和大小都能固定.这是什么原因啊!
上面注释的部分在2005上不能用.formwindowstate没有parse的方法.注释部分如何修改.

Answer 1

ReadSettings放到Form1_Load中看看
别放在构造方法里

Answer 2

我这里用按钮调用ReadSettings\SaveSettings没有问题
估计是调用的位置出现问题
SaveSettings放到Form1_FormClosed你可以通过多种测试缩小错误的范围，以便找到错误的关键触发原因。

Answer 3

我不是说了吗?在dispose()方法里面写过SaveSettings() 了.这个意思就是说当程序正常中断时,就调用SaveSettings()方法.这个贮存颜色和大小都行.可以保存Form位置不行啊!为什么 .
