根据MSDN,如果所有数组都是引用类型,那么为什么在给定的示例代码中,t2的新值不能反映t1的变化？
string[] data = new[] { "One","Two" };
var t1 = data[0];
Console.WriteLine(t1);
var t2 = t1;
t2 = "Three"; //assigning the new value,and this should reflect in t1
Console.WriteLine(t2);
Console.WriteLine(t1); // this should print 'Three',but it prints 'One'
Console.Read();

Arrays are mechanisms that allow you to treat several items as a
single collection. The Microsoft® .NET Common Language Runtime (CLR)
supports single-dimensional arrays,multidimensional arrays,and
jagged arrays (arrays of arrays). All array types are implicitly
derived from System.Array,which itself is derived from System.Object.
This means that all arrays are always reference types which are
allocated on the managed heap,and your app’s variable contains a
reference to the array and not the array itself.
