IEnumerable接口的不同扩展方法可用于此目的.

Distinct extension method of IEnumerable Interface can be used for this purpose.

string[] Countries = {
    "India", "Pakistan", "United States of America", "Germany",
    "Pakistan", "England", "Ireland", "India"};
var query = Countries.Distinct();
var distinctCountries = query.ToArray();

可以提供IEqualityComparer<T>参数来控制字符串的比较.

The IEqualityComparer<T> parameter can be supplied for controlling comparison of strings.
