如何通过BindingSource映射DataGridView内/嵌套类的属性？ [英] How to map properties of inner/nested classes in DataGridView through BindingSource?

问题描述

我有一个单独的数据层项目，有两个基本类：

I have a separate project for Data layer and there are two basic classes there:

[Serializable]
public class NesInfo
{
    public string FileName { get; private set; }
    public string Directory { get; private set; }
    public MapperInfo MapperInfo { get; set; }
}

和

[Serializable]
public class MapperInfo
{
    public string Number { get; set; }
    public string Prop1{ get; set; }
    public string Prop2 { get; set; }
}

现在我要我的DataGridView显示这样的列：

[FileName] [Directory] ​​[Number] [Prop1] [Prop2]

Now I want my DataGridView to Display columns like this:
[FileName][Directory][Number][Prop1][Prop2]

这使用BindingSource？

How I can achieve this using BindingSource?

我试过在我的DataGridView中使用我的 BindingSource ，而不是5列获取3（嵌套类被视为一列，内部属性应该在那里）：

I've tried using my BindingSource in my DataGridView, but instead of 5 columns, I get 3 (the nested class is treated like one column, where the inner properties should be there instead):

当尝试添加列时，我无法选择MapperInfo类的内部属性：

And I cannot select the inner properties of MapperInfo class when trying to add columns:

推荐答案

您可以创建一个包含所有属性的新类您希望在网格中显示，并将其与您现有的类别手动或使用第三方库（例如， AutoMapper）。然后将新类绑定到网格。

You can create a new class with all the properties that you want to be display in the grid and map it with your existing class either manually or using third-party libraries (ex. AutoMapper). Then bind the new class to Grid.

public class MyGridClass
{
    public string FileName { get; set; }
    public string Directory { get; set; }
    public string Number { get; set; }
    public string Prop1 { get; set; }
    public string Prop2 { get; set; }
}

NesInfo ni = ...

MyGridClass gc = new MyGridClass ( );
gc.FileName = ni.FileName;
gc.Directory = ni.Directory;
gc.Number = ni.MapperInfo.Number;
gc.Prop1 = ni.MapperInfo.Prop1;
gc.Prop2 = ni.MapperInfo.Prop2;
