c# - 使用 args 从另一个程序启动程序后丢失绑定

Question

这是第一个程序中代码的一部分，我在这里启动第二个程序。

        private void ExecuteStartCacherCommand(object parameter)
        {
            try
            {
                StringBuilder sb = new StringBuilder();
                sb.Append("\"" + ProductCode.BoxName + "\""); sb.Append(" ");
                sb.Append(LengthText); sb.Append(" ");
                sb.Append(WidthText); sb.Append(" ");
                sb.Append(HeightText); sb.Append(" ");
                sb.Append(L1); sb.Append(" ");
                sb.Append(L2); sb.Append(" ");
                sb.Append(StampTotalPrice);

                string arg = sb.ToString();

                Process p = new Process();
                p.StartInfo.FileName = "CacherPrices.exe";
                p.StartInfo.Arguments = arg;
                p.Start();
            }
            catch (Exception ex)
            {
                System.Console.WriteLine(ex.Message);
            }
        }

这是第二个程序中代码的一部分。

        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            try
            {
                string[] args = new string[10];

                ArgsIncome ai;

                if (e.Args.Length > 0)
                {
                    for (int i = 0; i < e.Args.Length; i++)
                    {
                        args[i] = e.Args[i];
                    }

                    ai = ArgsIncome.getSampleOfDataBase();
                    ai.Name = args[0];
                    ai.Length = args[1];
                    ai.Width = args[2];
                    ai.Height = args[3];
                    ai.L1 = args[4];
                    ai.L2 = args[5];
                    ai.Stamp = args[6];

                }
                else
                    ai = ArgsIncome.getSampleOfDataBase(); 
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }


            // загружаем главное окно.
            View.MainWindow window = new View.MainWindow();
            this.MainWindow = window;
            window.Show();

        }

问题： 当我从第一个程序启动第二个程序时，我拥有的所有绑定都消失了。当我使用 args 在调试中启动第二个程序时，一切正常

附加信息

public class ArgsIncome
    {
        public string Name { get; set; }
        public string Length { get; set; }
        public string Width { get; set; }
        public string Height { get; set; }
        public string L1 { get; set; }
        public string L2 { get; set; }
        public string Stamp { get; set; }

        private ArgsIncome()
        {
            Name = "Тип";
            Length = "0";
            Width = "0";
            Height = "0";
            L1 = "0";
            L2 = "0";
            Stamp = "0";
        }

        private static readonly object padlock = new object();
        private static ArgsIncome dataBase = null;

        public static ArgsIncome getSampleOfDataBase()
        {
            if (dataBase == null)
            {
                lock (padlock)
                {
                    if (dataBase == null)
                    {
                        dataBase = new ArgsIncome();
                    }
                }
            }
            return dataBase;
        }
    }

绑定示例

<TextBox Margin="5" Width="75" Text="{Binding Path=StampPrice,UpdateSourceTrigger=PropertyChanged}"/>

string _stampPrice;
    public string StampPrice
    {
        get
        {
            if (_stampPrice == null)
                _stampPrice = _ai.Stamp;
            return _stampPrice;
        }
        set
        {
            _stampPrice = value;
        }
    }

class MainWindowViewModel : ViewModelBase{}

public abstract class ViewModelBase : INotifyPropertyChanged, IDisposable{}
