c# - Pass Type as parameter and check -

-

i want build method accepts parameter type like

void m1(type t) {   // check type }

and call 

m1(typeof(int));

i have no idea how check type in method body.

i have tried 

if (t double)

but giving warning 

the given expression never provided type (double)

please me checking type of parameter.

if want check exact type, can use:

if (t == typeof(double))

that's fine double, given it's struct, can't inherited from.

if want perform more is-like check - e.g. check whether type compatible system.io.stream - can use type.isassignablefrom:

if (typeof(stream).isassignablefrom(t))

that match if t system.io.memorystream, example (or if it's system.io.stream itself).

i find myself having think work out way round call goes, target of call usually typeof expression.
