组合框索引发生变化后,另一个组合框必须填充List<string>
个值。我怎么能这样做?
例如:
表格(这是我现在的方式,但不正确):
private void cbSelectEditFunction_SelectedIndexChanged(object sender, EventArgs e)
{
cbSelectEditName.Items.Add(emp.FindEmployeeinFunction(cbSelectEditFunction.Text));
}
班级方法:
public List<string> FindEmployeeinFunction(string aFunction)
{
List<string> EmployeeListFunction = new List<string>();
foreach (Employee TempEmployee in EmployeeList)
{
if(TempEmployee.Function == aFunction)
{
EmployeeListFunction.Add(TempEmployee.Username);
}
}
return EmployeeListFunction;
}
希望这种方式可以理解。如果我忘记了什么,请告诉我!

我认为AddRange
是您正在寻找的方法
//Assuming you don't want to continually add new items use Clear()
cbSelectEditName.Items.Clear();
//Use AddRange to add the list. ToArray() is used to convert List<> to string[]
cbSelectEditName.Items.AddRange(emp.FindEmployeeinFunction(cbSelectEditFunction.Text).ToArray());
