嘿家伙

i有wpf数据网格以下列

hey guys
i have wpf Data Grid with below columns

IDStuff(int), Title(string), Type(string),  InitialBalance(int)

及以下课程

and below class

class stuffdt
{

    public int IDStuff { set; get; }
    public string Title { set; get; }
    public string Type { set; get; }

  }

但我有这个错误

but i have this error

Unable to cast object of type '<>f__AnonymousType1`4[System.Int32,System.String,System.String,System.Int32]' to type 'stuffdt'.

推荐答案

看看类似的问题：

读取WPF DataGrid中的单元格值 [ ^ ]

如何在wpf中获取datagrid特定的单元格值？ [ ^ ]

你不能强制转换动态对象。两者必须完全相同才能正确映射。



我建议你尝试使用listbox itemsource来检索你想要的记录。一些东西



喜欢：

you cannot typecast dynamic objects. the two have to be identical for them to be mapped correctly.

i'd suggest you try using the listbox itemsource to retrieve the records that you want. something

like:

private void dtstuff_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
...

stuffdt sd = {DataGridItemSource}[dtstuff.SelectedIndex]; 

//assuming the datagriditemsource is a list of type stuffdt

...
}
