示例1: Print
List<String> names = new List<String>();
names.Add("Bruce");
names.Add("Alfred");
names.Add("Tim");
names.Add("Richard");
// Display the contents of the list using the Print method.
names.ForEach(Print);
// The following demonstrates the anonymous method feature of C#
// to display the contents of the list to the console.
names.ForEach(delegate(String name)
{
Console.WriteLine(name);
});
void Print(string s)
{
Console.WriteLine(s);
}
/* This code will produce output similar to the following:
* Bruce
* Alfred
* Tim
* Richard
* Bruce
* Alfred
* Tim
* Richard
