我有一個這樣的 LINQ 查詢：
var getOnlyMP = from mpPoint in cmList where
mpPoint.Component.Contains("asd") ||
mpPoint.Component.Contains("dsa") ||
mpPoint.Component.Contains("123") ||
mpPoint.Component.Contains("456")
select new MP
{
MPName = mpPoint.Component,
X = mpPoint.PlaceX,
Y = mpPoint.PlaceY,
};
我想將“asd”、“dsa”、“123”、“456”存盤在一個陣列中，那么是否有可能在該陣列上回圈并動態地在 WHERE 子句之后的所有專案中進行比較？
uj5u.com熱心網友回復：
您可以.Any()與陣列一起使用，
var expectedStrings = new string[] {"asd", "dsa", "123", "456"};
var getOnlyMP = cmList.Where(mpPoint=>
expectedStrings.Any(x => mpPoint.Component.Contains(x)))
.Select(x => new MP
{
MPName = x.Component,
X = x.PlaceX,
Y = x.PlaceY,
});
在查詢表單中，
var expectedStrings = new string[] {"asd", "dsa", "123", "456"};
var getOnlyMP = from mpPoint in cmList where
expectedStrings.Any(x => mpPoint.Component.Contains(x)))
select new MP
{
MPName = mpPoint.Component,
X = mpPoint.PlaceX,
Y = mpPoint.PlaceY,
};
