c# - Using Where and ForEach to modify specific elements in a list -

-

if have list of objects have properties fruitname , numfruits , want pluralize fruitname numfruits greater 1, possible in single statement chaining where , foreach?

something like:

fruitlist.where(fl => fl.numfruits > 1).foreach(fl => fl.fruitname = fl.fruitname + "s");

i tried above , doesn't work. complains system.collections.generic.ienumerable doesn't contain definition foreach.

if want one-liner (it harder maintain) , want keep original list intact modify of elements, you'll have use full anonymous function. if need multiple statements (a block of code), you'll need include braces , statement-terminating semicolons below:

fruitlist.foreach(fl => { fl.fruitname = fl.numfruits > 1 ? fl.fruitname + "s" : fl.fruitname; });

this works on original list (no subset) , exact same thing structured foreach do.

i'm defining 2 entities following, strange behavior occurring: [table("clienttypes", schema="dbo")] public clienttype { [key] public int id { get; set; } public string name { get; set; } } [table("clients", schema="dbo")] public client { [key] public long id { get; set; } [foreignkey("clienttypeid")] public int clienttypeid { get; set; } public virtual clienttype clienttype { get; set; } } i'm getting clienttypeid property filled value, clienttype object filled nothing. can me this? thank all! the foreignkey attribute have on wrong property. the annotation may placed on foreign key property , specify associated navigation property name, or placed on navigation property , specify associated foreign key name. - source [foreignkey("clienttypeid")] should decorate public virtual clienttype clienttype instead, or change [foreignkey("clienttype...
