使用静态字段/属性创建静态类，如下所示：

 公共静态类DataContainer 
 {
 public static Int32 ValueToShare; 
} 
 

以多种形式使用它，如下所示：

  public void Form1_Method（）
 {
 DataContainer.ValueToShare = 10; 
} 

 public void Form2_Method（）
 {
 MessageBox.Show（DataContainer.ValueToShare.ToString（））; 
} 
 

hi i want to share a variable between 2 form. 2 forms is in the one project. In fact,i want a global variable in the project how can i do it?

Language: c# .net

Thanks

Create a static class with static field/property like following:

public static class DataContainer
{
    public static Int32 ValueToShare;
}

use it in multiple forms like following:

    public void Form1_Method()
    {
        DataContainer.ValueToShare = 10;
    }

    public void Form2_Method()
    {
        MessageBox.Show(DataContainer.ValueToShare.ToString());
    }
