SPFx-从DetailsList office ui fabric react控件获取所选行数据

我正在使用react类组件开发SPFX Web部件,并希望从DetailsList office ui fabric react控件中获取选定的行数据。我被DetailsList控件中select属性的实现所困扰。你能帮我实现Selection属性吗?

    export default class ProviderWebPartDemo extends React.Component<IProviderWebPartDemoProps, IProviderWebPartDemoState> {
  private _selection: ISelection<IObjectWithKey>;

  private _onItemsSelectionChanged = () => {
    
    this.props.onDepartmentSelected(this._selection.getSelection()[0] as IDepartment);
    
    this.setState({
      Department: (this._selection.getSelection()[0] as IDepartment)
    });

    
  }
  
  constructor(props: IProviderWebPartDemoProps, state: IProviderWebPartDemoState) {
    super(props);
    this.state = ({
      Department: {
        Id: 0,
        Title: ""
      },
      Deparments: []
    });
    this._selection = new Selection({
      onSelectionChanged: this._onItemsSelectionChanged,
    });  

   
  }

<DetailsList
      items={ this.state.Deparments}
      columns={ _departmentListColumns }
      setKey='Id'
      checkboxVisibility={ CheckboxVisibility.always}
      selectionMode={ SelectionMode.single}
      layoutMode={ DetailsListLayoutMode.fixedColumns }
      compact={ true }
      selection={this._selection }                                        
  />

I am stuck with implementation of selection property in the DetailsList control

上面的代码引发以下错误“类型'Selection'缺少类型'ISelection'中的以下属性:count、mode、canSelectItem、setChangeEvents和18个其他”
