    I have had Resource.ID not found errors. What was suggested (on this and other forums) was the save and quit VS, then delete the bin and obj folders along with the ResourceDesigner.cs file in the Resources folder. Restart VS and rebuild. That has worked for me.

    Try to use the following code

    var resourceId = (int)typeof(Resource.Drawable).GetField("").GetValue(null);

    @RonNYC I followed your description but won't work, each time getting id 0 on which FileNotFoundException occured

    This exception is thrown by the resource APIs when a requested resource can not be found.
    Could you post detailed information of Exception?

    @yelinzh Android.Content.Res.Resources+NotFoundException: Resource ID #0x0 thrown, because of id returned each time 0 ,I changed file name and folder as well .

    Resources.GetIdentifier("my_fileName","Asstes",My_Pakage_Name); the fault is in GetIdentifier(...).
    i change 2nd parameter to drawable and 1st to my_image.png , but again id return 0
    i think problem is in Method parameters, may be some thing is missing somewhere.

    Change 'Asstes' to 'Assets'.
