.NET中的全局变量(或替代)最佳实践

public class GlobalVariables
{
    private static GlobalVariables instance;

    private GlobalVariables() {}

    public static GlobalVariables Instance
    {
        get
        {
            if (instance == null)
            {
                instance = new GlobalVariables();
            }

            return instance;
        }
    }

    public string MyGlobalVariable { get; set; }
}

GlobalVariables.Instance.MyGlobalVariable = "Hello, world!";

public static class GlobalVariables
{
    public static string MyGlobalVariable { get; set; }
}

GlobalVariables.MyGlobalVariable = "Hello, world!";
