Lete乐特自制实用工具(C# - .NET Framework4.5)

由于上次使用Java编写的实用工具https://lete114.github.io/article/986f7d9c.html

Java写窗体程序的优缺点

优点:

  1. 可跨平台

缺点:

  1. Java程序依赖JVM(Java虚拟机)
  2. 由于JVM是存储在jre下的(而Java程序又依赖JVM(Java虚拟机))jre占用内存高达200MB

C#写窗体程序的优缺点

由于Java程序不便于携带,这次我使用C#编写

优点:

  1. 体积小(小于1MB)
  2. 便于携带
  3. 便于编写(随意拖动按钮图标等)

缺点:

  1. C#依赖 .NET Framework
    (这个不要紧,大多数电脑都会装有 .NET Framework,玩游戏的应该需要装游戏运行库,运行库里就包含有 .NET Framework)
