读写注册表的样码:
void SaveSettings()
{
RegistryKey softwareKey = 
Registry.LocalMachine.OpenSubKey("Software", true);
RegistryKey wroxKey = softwareKey.CreateSubKey("WroxPress");
RegistryKey selfPlacingWindowKey = 
wroxKey.CreateSubKey("SelfPlacingWindow");
selfPlacingWindowKey.SetValue("BackColor", 
(object)BackColor.ToKnownColor());
selfPlacingWindowKey.SetValue("Red", (object)(int)BackColor.R);

你在注册表里选择一个根项(或者自己建一个项):
在右面的框里右键新建字符串:名称你自定,然后在属性窗口里的VALUE栏里输入以下其中一个:
[EDITA1]         -->对应文本框A的第1个输入框
[EDITA2]         -->对应文本框A的第2个输入框
[EDITA3]         -->对应文本框A的第3个输入框
[EDITA4]         -->对应文本框A的第4个输入框
这样文本框输入的值就可以保存到注册表了.
