Difference between the System.Array.CopyTo() and System.Array.Clone()

Question

What’s the difference between the System.Array.CopyTo() and System.Array.Clone()?

Answer 1

object[] myarray = new object[] { "one", 2, "three", 4, "really big number", 2324573984927361 };

//create shallow copy by CopyTo
//You have to instantiate your new array first
object[] myarray2 = new object[myarray.Length];
//but then you can specify how many members of original array you would like to copy 
myarray.CopyTo(myarray2, 0);

//create shallow copy by Clone
object[] myarray1;
//here you don't need to instantiate array, 
//but all elements of the original array will be copied
myarray1 = myarray.Clone() as object[];

//if not sure that we create a shalow copy lets test it
myarray[0] = 0;
Console.WriteLine(myarray[0]);// print 0
Console.WriteLine(myarray1[0]);//print "one"
Console.WriteLine(myarray2[0]);//print "one"
