foreach语句中的多个where子句

Question

我有以下语句:

foreach (var textBlock in scoresGrid.Children.OfType<TextBlock>().Where(three => three.Name.Contains("Three")))

我怎样才能使它变成where name contain three or four呢?

请帮助。由于

Answer 1

使用或||运算符组合where子句中的条件。

foreach (var textBlock in scoresGrid.Children.OfType<TextBlock>()
           .Where(three => three.Name.Contains("Three") || three.Name.Contains("Four")))

Answer 2

string[] names = { "Three", "Four" } ;
foreach (var textBlock in scoresGrid.Children.OfType<TextBlock>()
                   .Where(tb => names.Any(name => tb.Name.Contains(name))))

我也认为你的foreach语句有点难读。首先获得过滤的textBlocks。

Answer 3

可以使用逻辑运算符。For or是'||'>().Where(three => three.Name.Contains("Three") || three.Name.Contains("Four")))
