将值传递给其他表单 [英] Pass Values to Other Form

问题描述

大家好！我如何将值传递给其他形式？我想将字符串values传递给DataGridView表格



我的代码如下：

Hi Everyone! How can i pass values to other form? i want to pass the string "values" to DataGridView form

My Code Below:

static class Program
    {
        static void Main()
        {
            string values = "T";
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            DataGridView a = new DataGridView();
            if (values == "T")
            {
                a.ShowDialog();
            }
            else
            {
                a.Show();
            }
         }
     }

DataGridView表格代码

DataGridView Form Code

public partial class DataGridView : Form
   {
       public DataGridView()
        { 
           InitializeComponent();
           
           MessageBox.Show(values);
        }
   }

我希望DataGridView表单显示字符串values。请提出想法或解决方案谢谢！

I want the DataGridView form to display the string "values". Please give idea or solutions Thanks!

推荐答案

您好新生儿，

您只需在DataGridView表单中创建一个全局变量，然后将值赋给program.cs中的变量如下所示在DataGridView.cs文件中




声明变量



public String values = string.Empty;





从program.cs文件中分配值，以便你可以访问该值。



谢谢

Hi Fresher boy,
You just create a global variable in DataGridView form then assign the value to that variable in program.cs like below

in DataGridView.cs file
Declare a variable

public String values= string.Empty;


Assign the value from program.cs file so that u can access the value.

Thank you

这是一个受欢迎的问题形成合作。最强大的解决方案是在表单类中实现适当的接口，并传递接口引用而不是引用Form的整个实例。有关更多详细信息，请参阅我以前的解决方案：如何以两种形式复制列表框之间的所有项目 [ ^ ]。



另请参阅此处的其他解决方案讨论。如果应用程序足够简单，解决方案就像在一个表单中声明一些 internal 属性并将对一个表单的实例的引用传递给另一个表单的实例一样简单形成。对于更复杂的项目，这种违反严格封装的样式和松散耦合可能会增加代码的意外复杂性并引发错误，因此封装良好的解决方案将是优惠。

This is the popular question about form collaboration. The most robust solution is implementation of an appropriate interface in form class and passing the interface reference instead of reference to a "whole instance" of a Form. Please see my past solution for more detail: How to copy all the items between listboxes in two forms[^].

Please also see other solutions in this discussion. If the application is simple enough, the solution could be as simple as declaring of some internal property in one form and passing a reference to the instance of one form to the instance of another form. For more complex projects, such violation of strictly encapsulated style and loose coupling could add up the the accidental complexity of the code and invite mistakes, so the well-encapsulated solution would be preferable.
