How about simply:
var tags = new List<Tag> {
new Tag("1", "A"),
new Tag("2", "B"),
new Tag("3", "C"),
};
List<string> names = tags.ConvertAll(t => t.Name);
No Linq needed, and if you need an array, call ToArray().
Comments
var names = from t in tags
select t.Name;
Something like this will give you an IEnumerable over names, just use .ToArray() if you wan't array of those.

or simply tags.Select(t => t.Name);
return (from Tag in MyTagArray select Tag.Name).ToArray();
Comments
string[] tagArray = (from t in tagList select t.Name).ToArray();

I assume that you want something like this :
public List<string> GetNamesOfTag(List<Tag> tags)
{
List<string> Name = new List<string>();
foreach(Tag item in tags)
{
Name.Add(item.name);
}
returns Name;
}

@Charlie : Everyone wrote the code in LINQ, I wanted show something different.

@Aaron fair enough, good for C#2. You should edit your answer to return an array of strings rather than a list like the question says though.
To best use IEnumerable interface. Otherwise you can use linq queries for that or basic foreach loop
