C# WPF DataGrid绑定到列表中类的属性

我正在尝试将一个

数据网格

绑定到一个

列表

，以便在列表执行时自动更新

在my xaml.cs中：

private DataStorage dataStorage = new DataStorage();

xaml：

和文件类：

private string fileName { get; set; }
private long fileSize { get; set; }
private string fileImage { get; set; }
private string fileLocation { get; set; }
private string fileType { get; set; }

我通过以下方式向列表中添加新文件：

foreach (string fileDropped in files)
{
    File file = new File(fileDropped);
    dataStorage.AddFileToList(file);
}

列表中正在填充这些文件对象，并且属性不为null

我的问题是让

DataGridView

用它更新

我的错误：

System.Windows.Data Error: 40 : BindingExpression path error: 'fileName' property not found on 'object' ''File' (HashCode=1820782)'. BindingExpression:Path=fileName; DataItem='File' (HashCode=1820782); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'fileType' property not found on 'object' ''File' (HashCode=1820782)'. BindingExpression:Path=fileType; DataItem='File' (HashCode=1820782); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')

使用

observedcollection

而不是

List

，还可以使用

public

类

文件的成员

public ObservableCollection<File> listOfFiles = new ObservableCollection<File>();

您是否已将类“File”的成员更改为公共成员？
System.Windows.Data Error: 40 : BindingExpression path error: 'fileName' property not found on 'object' ''File' (HashCode=1820782)'. BindingExpression:Path=fileName; DataItem='File' (HashCode=1820782); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')

public ObservableCollection<File> listOfFiles = new ObservableCollection<File>();

  public string fileName { get; set; }
  public long fileSize { get; set; }
  public string fileImage { get; set; }
  public string fileLocation { get; set; }
  public string fileType { get; set; }
