C＃-编译器错误

Question

I am making an app in C# using Mono and I am referencing two libraries which is giving me an error. How can I mae it so that i only reference one.

this is the error i am getting

Error 1 The type 'System.Drawing.RectangleF' exists in both 'c:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\MonoAndroid\\v2.3\\Mono.Android.dll' and 'c:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework\\MonoTouch\\v4.0\\monotouch.dll' C:\\Users\\cmtc\\documents\\visual studio 2012\\Projects\\BoostITAndroid\\BoostITAndroid\\HelperClasses\\RightAlignedEntryElement.cs 19 50 BoostITAndroid

how do I make it so I only select System.Drawing.RectangleF from one of the libraries

Answer 1

Use Alias referencing:

using Name1 = Android.Mono;
using Name2 = Monotouch;

Wherever you are using the reference, use the alias name that you wanted to use, for example;

Name1.RectangleF rectF = new Name1.RectangleF();

This way you keep both reference.

Answer 2

For me what solved was to remove an unwanted reference in the android project: Xamarin.iOS or check if you have Android.Mono on your iOS project. If you do have such reference, remove it, close visual studio and rebuild
