How to embed dynamic OR condition after WHERE statement in linq query c#-CodePudding

I have a LINQ query like this:

    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,                                 
    };

I want to store "asd", "dsa", "123", "456" in an array, so is there a possibility to loop through on that array and make the comparing in all items after the WHERE clause dynamically?

CodePudding user response：

You can use .Any() with an array,

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,                                 
                });

In query form,

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,                                 
   };
