解决

感谢HAR07帮助我，以及任何已经评论过的人！

public partial class xamlAuditorDashboard : Window
{
    cEvolve_SP sp = new cEvolve_SP(Properties.Settings.Default.AppConnectionString);
    List<cAuditTasksEntity> _tasks;
    cAuditUserEntity _loggedInUser;
    public xamlAuditorDashboard(cAuditUserEntity loggedInUser)
    {
        _loggedInUser = loggedInUser;
        InitializeComponent();
        _tasks = new List<cAuditTasksEntity>();
        Refresh();
    }

    private void Refresh()
    {

        var _AuditUserId = _loggedInUser;
        cAuditUserEntity user = _AuditUserId as cAuditUserEntity;

        int userid = user.AuditUserId;

        _tasks = sp.GetTasksByUser(userid).ToList();

        var result = (from cAuditTasksEntity tasks in _tasks
                      select tasks.TaskId).ToList();
        cmbToDoList.ItemsSource = result;

    }

    private void btnAudit_Click(object sender, RoutedEventArgs e)
    {
        var Audit = cmbToDoList.SelectedItem;

        var _TransactionId = Audit;

        cAuditTransactionsEntity transaction = _TransactionId as cAuditTransactionsEntity;

        string transactionid = transaction.TransactionId;

        sp.GetTransactionInfo(transactionid);


    }

我想要做的是，从TaskId我想找到TransactionId。

从我的刷新方法中的代码中获取LoggedOnUser并搜索TaskTable然后找出ID旁边的任何任务，然后在一个中显示`TaskIds'那页上的组合框。

我要做的是当他们点击组合框中的TaskId并单击“新建审核”时，另一个页面将加载并显示所有不同的信息。

这是TaskTable，TaskID就是那里出现的组合框。

当他们从那里从组合框中选择一个新的ID并点击下一步时，我需要它来找到他们点击的TaskId旁边的transactionId，然后带回来：

圈子中的所有信息？

编辑：

cAuditTasksEntity：

namespace DAL
{
[Table(Name = "Audit_Tasks")]
public class cAuditTasksEntity
{

    private int _TaskId;
    private int _AuditUserId;
    private string _TransactionId;
    private string _TaskTypeId;
    private DateTime _Date;
    private string _AuditStatus;


    [Column(DbType = "INT", IsPrimaryKey = true, IsDbGenerated = true)]
    public int TaskId
    {
        get { return _TaskId; }
        set { _TaskId = value; }
    }

    [Column(DbType = "INT")]
    public int AuditUserId
    {
        get { return _AuditUserId; }
        set { _AuditUserId = value; }
    }

    [Column(DbType = "CHAR(32)")]
    public string TransactionId
    {
        get { return _TransactionId; }
        set { _TransactionId = value; }
    }

    [Column(DbType = "CHAR(32)")]
    public string TaskTypeId
    {
        get { return _TaskTypeId; }
        set { _TaskTypeId = value; }
    }

    [Column(DbType = "DATETIME")]
    public DateTime Date
    {
        get { return _Date; }
        set { _Date = value; }
    }

    [Column(DbType = "VARCHAR(255)")]
    public string AuditStatus
    {
        get { return _AuditStatus; }
        set { _AuditStatus = value; }
    }



}
}

我看到的属性也是这4个：

ToString();
GetHashCode();
GetType();
Equals();

EDIT2：

这是Audit.GetType();显示的内容，但我不明白？

我添加了这段代码：

var result = Audit.GetType();

然后此设置结果等于：

{Name = "Int32" FullName = "System.Int32"

我认为这就是你要找的，在给定TaskId的情况下得到transactionId：

var _TransactionId = (from task transactionid in _tasks 
                       where task.TaskId == (int)cmbToDoList.SelectedItem
                       select task.TransactionId).FirstOrDefault();

通过用户名查找ID？
