There are several ways to pass values between WinForms windows:<\/p>\n

    \n
  1. Constructor: Pass parameters to the window’s constructor when creating an instance of the form. For example:<\/li>\n<\/ol>\n
    Form2 form2 = new<\/span> Form2(valueToPass);\r\nform2.Show();\r\n<\/code><\/pre>\n
      \n
    1. Properties: values can be passed between forms by defining common properties. For example:<\/li>\n<\/ol>\n
      public<\/span> partial<\/span> class<\/span> Form2<\/span> : Form<\/span>\r\n{\r\n    public<\/span> string<\/span> ValueToReceive { get<\/span>; set<\/span>; }\r\n\r\n    public<\/span> Form2<\/span>()<\/span>\r\n    {\r\n        InitializeComponent();\r\n    }\r\n}\r\n<\/code><\/pre>\n
      Setting the value of a property in another window and accessing it:<\/p>\n
      Form2 form2 = new<\/span> Form2();\r\nform2.ValueToReceive = \"Value to pass\"<\/span>;\r\nform2.Show();\r\n<\/code><\/pre>\n
        \n
      1. Static variables: It is possible to define static variables in a static class to store passed values. For example:<\/li>\n<\/ol>\n
        public<\/span> static<\/span> class<\/span> Globals<\/span>\r\n{\r\n    public<\/span> static<\/span> string<\/span> ValueToPass { get<\/span>; set<\/span>; }\r\n}\r\n\r\n\/\/ \u5728\u4e00\u4e2a\u7a97\u4f53\u4e2d\u8bbe\u7f6e\u503c<\/span>\r\nGlobals.ValueToPass = \"Value to pass\"<\/span>;\r\n\r\n\/\/ \u5728\u53e6\u4e00\u4e2a\u7a97\u4f53\u4e2d\u83b7\u53d6\u503c<\/span>\r\nstring<\/span> value<\/span> = Globals.ValueToPass;\r\n<\/code><\/pre>\n
