It throw an exception while creating collator for myanmar.

This throws an ArgumentException because there are no predefined collation rules for my-MM in ICU. However, there are rules for my, so the following would work:

var cultureInfo = new CultureInfo("my");

Or you could allow the fallback to my by passing FallBackAllowed:

using (var collator = Collator.Create(cultureInfo.Name, Collator.Fallback.FallbackAllowed))
{
}

You can see the predefined collators by looking at the icu4c source tree.

The full code to sort a list of strings:

var list = new List<string> {"foo", "baz", "bar", "zoo"};

using (var collator = Collator.Create("en-US"))
{
    list.Sort((s1, s2) => collator.Compare(s1, s2));
}
