actual type, such as ExampleClass, String, or Type. The following example causes CS0246 because an object of type Type was used where an actual type was expected. the using directive for the namespace for this attribute, The following example generates CS0246 because a necessary using directive is missing. The root problem may be with some other type in another assembly. If you verify with Object Browser that the assembly contains the namespace, try removing the using directive for the namespace and see what else breaks. Im on Unity 2019.1.12f1 and the most recent version of InputSystem. There are no compile errors or namespace conflicts. The field does not show up in the inspector, regardless of whether its public or serialized. If you haven’t successfully accessed the reference yet, use the Object Browser to inspect the assembly that is supposed to contain this namespace and verify that the namespace is present. The c script that is generated from the new Input System cannot be assigned to a variable in a monobehaviour script. csproj file and/or your local source file. If all references seem to be correct, look in your source control history to see what has changed in your. Do you need to reinstall a NuGet package?

Unity 2019 compiler error using system.collections; code#
If you get this error in code that was previously working, first look for missing or unresolved references in Solution Explorer. To avoid the error, fully qualify List. The following declaration generates CS0246. The using directive for does not prevent the error. The following example generates CS0246 because the type List is not fully qualified. Then you get error CS0246.ĭid you use a using alias directive without fully qualifying the type name? A using alias directive does not use the using directives in the source code file to resolve types. NET Framework 4.6.1 and use the type from the project that is targeting. If you omit the using directive in the previous example, you must write ds to declare ds instead of DataSet ds.ĭid you use a variable or some other language element where a type was expected? For example, in an is statement, if you use a Type object instead of an actual type, you get error CS0246.ĭid you reference the assembly that was built against a higher framework version than the target framework of the program? Or did you reference the project that is targeting a higher framework version than the target framework of the program? For example, you work on the project that is targeting. Full qualification means that you specify both the namespace and the type each time you refer to the type in your code. However, if you omit the directive, you must fully qualify the DataSet type when referring to it. For example, because DataSet is located in the System.Data namespace, you need the following directive at the beginning of your code: using System.Data. Second, you need a using directive for the namespace where DataSet is located. First, you need a reference to the assembly that contains the definition for the DataSet type. To use the DataSet type, you need two things. If the error is for a type name, did you include the proper using directive, or, alternatively, fully qualify the name of the type? Consider the following declaration: DataSet ds. For more information, see Managing references in a project However, if your project does not reference the assembly Accessibility.dll, error CS0246 is reported. If the error is for a namespace name, did you add a reference ( References) to the assembly that contains the namespace? For example, your code might contain the directive using Accessibility. For example, Dataset ds generates CS0246 because the s in Dataset must be capitalized. This often occurs because the casing used in the name of the type is not correct. The following situations cause compiler error CS0246.ĭid you misspell the name of the type or namespace? Without the correct name, the compiler cannot find the definition for the type or namespace. Or, there might be an issue with the assembly you are trying to reference. You might have forgotten to reference ( References) the assembly that contains the type, or you might not have added the required using directive. I have the script InterfaceContainer.cs as follows: using System.The type or namespace name 'type/namespace' could not be found (are you missing a using directive or an assembly reference?)Ī type or namespace that is used in the program was not found. I am using Unity 2019.3.13f1 and Visual Studio Community 2019 version 16.5.4.
