C# WPF Datagridview将动态属性更改为从组合框中选择的类型

public class MyDataModel : INotifyPropertyChanged
{
    private string name;
    private object value;

    public string Name
    {
        get { return name; }
        set
        {
            name = value;
            OnPropertyChanged(nameof(Name));
        }
    }

    public object Value
    {
        get { return value; }
        set
        {
            this.value = value;
            OnPropertyChanged(nameof(Value));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
