usingSystem;
namespaceDelegateDemo
{
classProgram
{
privatedelegateintCacu(stringstr);
staticvoidMain(string[]args)
{
//1
Cacucacu=newCacu(CacuInstance);
Console.WriteLine(cacu("Hello,Wrold"));
//2
Cacucacu1=newCacu(delegate(stringstr){returnstr.Length;});
Console.WriteLine(cacu1("Hello,Wrold"));
//3
Cacucacu2=newCacu((str)=>{returnstr.Length;});
Console.WriteLine(cacu2("Hello,Wrold"));
}
staticintCacuInstance(stringstr)
{
returnstr.Length;
