Pass in variable instance from another method

Question

I have an on execute method that has variable "item". I need to pass that variable to my other method "IsStatusChangeValid"

Below is what I currently have, but so far its not working. I looked at some related questions on stack overflow such as Accessing Variables From Another Method and looked at some parameter passing tutorials/examples online such as Parameter Passing in C# but I have been unable to apply the information properly.

protected override CommandResult OnExecute()
{
    var item = ItemViews.ItemGet(itemId);

    if (IsStatusChangeValid())
    { 
        ...
    }
    else
    { 
        ... 
    }
}

public bool IsStatusChangeValid(item)
{
    // ONLY IF SET EXISTS
    if (item.ItemSets.Count > 0)
    {
        // CHECK IF ITEM STATUS IS CHANGED TO "CLOSED-VOIDED"
        if (newDescription.Equals("Closed-Voided"))
        {
            // IF THERE ARE NON-VOIDED SETS, DO NOT ALLOW THE STATUS CHANGE
            if (item.ItemSets.Any(p => p.SetStatusID != SetStatusIDConstants.Voided))
            {
                return false;
            }
        }
    }
    return true;
}

How are you trying to call the second method? from with inside the OnExecute method? What did you try that didn't work (and why didn't it work)? — Sayse

Sayse: I have an if statement in OnExecute that does if (IsStatusChangeValid) {do work} else {stop and post warning} I've tried IsStatusChangeValid(item) and IsStatusChangeValid(ItemViews item) and IsStatusChangeValid(Item item) The first one throws an error under item. The second two throw errors from within the IsStatusChangeValid method. — AtlasBowler

And how have you tried to use it? Your second link has a fairly decent example under Value parameters — Sayse

sorry. just updated that previous comment with what I have tried. — AtlasBowler

IsStatusChangeValid(item) is correct, what error did you get — Sayse

There are two mistakes you made in your code

The declaration of the method

You must define what type a parameter is

public bool IsStatusChangeValid(Item item)

You must pass in an item into the call of the method

if(IsStatusChangeValid(item))

@AtlasBowler - No worries, I've just seen that MSDN has a page on passing parameters that you may find more useful
