c# - Why there is no ForEach extension method on IEnumerable? -

inspired question asking missing zip function:

why there no foreach extension method in enumerable class? or anywhere? class gets foreach method list<>. there reason why it's missing (performance)?

there foreach statement included in language job of time.

i'd hate see following:

list.foreach( item => {     item.dosomething(); } ); 

instead of:

foreach(item item in list) {      item.dosomething(); } 

the latter clearer , easier read in situation, although maybe bit longer type.

however, must admit changed stance on issue; foreach() extension method indeed useful in situations.

here major differences between statement , method:

• type checking: foreach done @ runtime, foreach() @ compile time (big plus!)
• the syntax call delegate indeed simpler: objects.foreach(dosomething);
• foreach() chained: although evilness/usefulness of such feature open discussion.

those great points made many people here , can see why people missing function. wouldn't mind microsoft adding standard foreach method in next framework iteration.
