c# - Comparing generics: A "master-type" IEnumerable<> that is generic, but matches all specific types (IEnumerable<int>, IEnumerable<object>, ...)? -

i want to compare typeof(ienumerable<>) types of various specific classes of ienumerable, e.g.

compare(typeof(ienumerable<>), typeof(ienumerable<object>))   // should return true compare(typeof(ienumerable<>), typeof(ienumerable<int>))      // should return true compare(typeof(ienumerable<>), typeof(ienumerable<myclass>))  // should return true compare(typeof(ienumerable<>), typeof(ienumerable))           // should return false because ienumerable not generic ienumerable<> type 

how can this? common methods such == or isassignablefrom return false above examples.

---

probably not necessary question, background:

i'm writing conversion class convers object other type. i'm using attributes (xlconverts):

public class xlconvertsattribute : attribute {     public type converts;     public type to; } 

to flag type each methods converts into. 1 of conversion methods converts object ienumerable:

[xlconverts(converts = typeof(object), = typeof(ienumerable<>))]     public static ienumerable<t> toienumerable<t>(object input)     {     // .... } 

then have more general method

public static object convert(object input, type totype) {     // ... } 

which uses reflection method has xlconverts.to == totype, reflects own class find approrpaite conversion method given desired target type.

now when call convert(input, typeof(ienumerable)), supposed find method toienumerable reflection. can flag [xlconverts(to = typeof(ienumerable<>)), , ienumerable<> not ienumerable, won't find method.

i'm aware using ienumerable instead of ienumerable<> job here, explicitly need use generic ienumerable<> because later on, want further reflection , filter out methods convert generic type.

thanks!

public static bool compare(type generictype, type t) {     return t.isgenerictype && t.getgenerictypedefinition() == generictype; }
