将数组转换为数据表

  • 772

我有以下类型的数组：

public class UserInfo
{
    public Guid UserId { get; set; }

    public string FIO { get; set; }
}

如何将此数组中的 UserId 数据添加到 DataTable？尝试过这种方式，但它不起作用：

public class ViewModel
{
    public ViewModel()
    {
        Workers = new ObservableCollection<UserInfo>();
    }

    public ICollection<UserInfo> Workers { get; set; }

    protected override async Task InitializeAsync()
    {
        var workers = await _procedures.GetUsers();
        Workers.ReplaceRange(workers);
    }

    var idWorkers = new DataTable();

    foreach (var worker in Workers)
    {
        idWorkers.Rows.Add(worker.UserId);
    }
}
c#

    解决方案：

    public class ViewModel
{
    public ViewModel()
    {
        Workers = new ObservableCollection<UserInfo>();
    }

    public ICollection<UserInfo> Workers { get; set; }

    protected override async Task InitializeAsync()
    {
        var workers = await _procedures.GetUsers();
        Workers.ReplaceRange(workers);
    }

    var idWorkers = new DataTable();
    var column = new DataColumn { DataType = typeof(Guid) };
    idWorkers.Columns.Add(column);

    foreach (var worker in Workers)
    {
        idWorkers.Rows.Add(worker.UserId);
    }
}
