Projects\boeing\showPMACfg\vuePMAcfg\vuePMAcfg.cs( 88):

Static member 'vuePMAcfg.pmaDataHash.pmaDataHash1' cannot

be accessed with an instance reference; qualify it with a

type name instead

OK I have this class And the hash and the function shows

up in type ahead. I tried declaring it and later accessing

it like this:

private vuePMAcfg.pmaDataHash pmaDataObj;

...

pmaDataShareArray.Add(pmaDataObj.pmaDataHash1);

But I get the error above ... if I try

private vuePMAcfg.pmaDataHash pmaDataObj = new

vuePMAcfg.pmaDataHash(); ... I get the same error.

What does the error mean and how do I get to the items &

function ? Thanks

public class pmaDataHash

{

public pmaDataHash()

{

}

public static Hashtable pmaDataHash1 = new

Hashtable();

public string GetFolderBylevel(string filePath,int level)

}

    • Hi andrew,

      The static methods/properties or variables need to be qualified with the

      class name:

      pmaDataShareArray.Add(pmaDataObj.pmaDataHash1) needs to be written like:

      pmaDataShareArray.Add( pmaDataHash.pmaDataHash1);

      See that the pmaDataHash1 belong to the class as a whole, ont to a

      particular instance, therefore all the instances(objects of type

      pmaDataHash) will share the same pmaDataHash1.

      What is what you are trying to do anyway?

      Hope this help,

      --

    • Hello Andrew,

      The error message already showed where the problem is.

      In the code, the pmaDataHash1 is a static member of pmaDataHash class, it

      must be refer to by pmaDataHash's static function and it must be associated

      with this type, not an instance of this type.

      In your code listed out, I can not find the place you refer to pmaDataHash1

      data member, but from the error message, you maybe associate it with an

      instance.

      Hope this helps.

      Best regards,
