部分匹配ObservableCollection<string>对象

就像盖布在评论中回答的那样。

但更具体一点

.Where(x => x.IndexOf("Some",StringComparison.InvariantCultureIgnoreCase) != -1)

好吧,我实际上用谷歌搜索了更多,找到了一个更好的解决方案:

可以使用indexof()并传递StringComparison.OrdinalIgnoreCase

string title = "STRING";
bool contains = title.IndexOf("string", StringComparison.OrdinalIgnoreCase) >= 0;

更好的方法是为字符串定义新的扩展方法:

public static bool Contains(this string source, string toCheck, StringComparison comp)
{
    return source.IndexOf(toCheck, comp) >= 0;
}

string title = "STRING";
bool contains = title.Contains("string", StringComparison.OrdinalIgnoreCase);

所以现在我已经在我的源代码中实现了它,如下所示:

foreach (string source in SourceStrings)
{
    // Code for some pre-reqs here

    if (source.IndexOf(Pattern, StringComparison.OrdinalIgnoreCase) >= 0)
    {
        subset.Add(source);
    }

    // Finish up anything else I had to do here
}
