如何获取使用foreach循环创建的组合框的值成员

Question

如何获取使用foreach循环创建的组合框的值成员？它不显示值成员。

我下面的代码：

DataSet dsLoadWorkHourId = new DataSet(); 
dsLoadWorkHourId = Workhour.LoadWorkId(); 
foreach (DataRow row in dsLoadWorkHourId.Tables[0].Rows) 
{ 
    cmbWorkHourId.Items.Add(row["SHIFT"].ToString()); 
} 

Answer 1

你应该做的，而这样的

DataSet dsLoadWorkHourId = new DataSet(); 
dsLoadWorkHourId = Workhour.LoadWorkId(); 
cmbWorkHourID.DataSource = dsLoadWorkHourId.Tables[0] 
cmbWorkHourID.DisplayMember = "SHIFT"; 
cmbWorkHourID.ValueMember = "SHIFTID"; //Use the ID column name here 

如果你想比

DataSet dsLoadWorkHourId = new DataSet(); 
dsLoadWorkHourId = Workhour.LoadWorkId(); 
cmbWorkHourID.DataSource = dsLoadWorkHourId.Tables[0] 
cmbWorkHourID.DisplayMember = "SHIFTID"; //use the ID column name here 
cmbWorkHourID.ValueMember = "SHIFTID"; //Use the ID column name here
