C ＃ traversal set

1. Enumeration type  

// Traversing enumeration types Sample Enumeration names of foreach (string sp in Enum.GetNames(typeof(Sample))) { ary.Add(sp); } // Traversing enumeration types Sample Each enumeration value of foreach (string sp in Enum.GetValues(typeof(Sample))) { ary.Add(sp); }

2. Traverse ArrayList(Queue、Stack) 
Here we use string For example , Of course ArrayList Elements in can be any data type , Confirm when traversing ArrayList All elements in are of the same data type . 

// The traversal element is string Type of queue  
foreach (string text in arraylist) 
{ 
ary.Add(text); 
} 

In addition, traversal Queue Queue and Stack Stack in the same way ArrayList Basically the same , You can use foreach To loop through , It's just that one is first in first out and the other is first in first out . 

ArrayList list = new ArrayList();
//for Traverse 
for (int i = 0; i < list.Count; i++)
{
  SE se = (SE)list[i];
  Console.WriteLine(se.Name);
}
//foreach Traverse 
foreach (Object obj in list)
{
  SE se = (SE)list[i];
  Console.WriteLine(se.Name);
}
3.Winform Controls in forms  
// Traverse to find the control in the main form , And remove the qualified controls from the form  
foreach (Control ctl in this.Controls) 
{ 
// Get and judge the control type or control name  
if (ctl.GetType().Name.Equals("ListBox") || ctl.Name.Equals("listBox1")) 
this.Controls.Remove(ctl); 
}
