非静态字段、方法或属性“System.Windows.Forms.FileDialog.FileName.get”(CS

本文关键字：FileName FileDialog Forms get CS Windows System 字段 静态 方法 属性 | 更新日期: 2023-09-27 18:33:04

每当我尝试运行它时，我都会收到此错误：非静态字段、方法或属性"System.Windows.Forms.FileDialog.FileName.get"（CS0120）需要对象引用

我对如何解决感到非常困惑，因为我已经看到了其他论坛，但他们与我的问题不同。

非静态字段、方法或属性“System.Windows.Forms.FileDialog.FileName.get”(CS

OpenFileDialog newgame = new OpenFileDialog();
string FilePath = OpenFileDialog.FileName;

访问 FileName 时，您在静态上下文中引用OpenFileDialog;您需要使用 OpenFileDialog 的newgame实例才能检索 FileName 属性：

OpenFileDialog newgame = new OpenFileDialog();
string FilePath = newgame.FileName;
