Why is Resharper telling me my string[] is never assigned?

Question

On this declaration:

string[] TardyEvenEmorys;

...Resharper tells me, "Field 'TardyEvenEmorys' is never assigned."

Later on in the code, assignments are made to the string[]:

TardyEvenEmorys[1] = string.Empty;
TardyEvenEmorys[2] = string.Empty;
TardyEvenEmorys[3] = string.Empty;
TardyEvenEmorys[4] = string.Empty;

...and then actual values are conditionally added:

foreach (KeyValuePair<int, string> entry in itemNumberTardyPairs)
{
    TardyEvenEmorys[entry.Key] = entry.Value;

. . .

...finally, those values are used in this way:

string url = GetTardyFilename(TardyEvenEmorys[Number]);

So what is Resharper telling me? That I should instantiate the string[] on declaration, or...???

Answer 1

You're assigning individual elements of the array, but never actually creating the array itself.

You need to instantiate the array somewhere. This could be during the declaration, or later. For example, to do it during the declaration, you would need to add:

string[] TardyEvenEmorys = new string[5]; // Some appropriate length

Without this, the first time you assign one of the elements, you'll get an exception since the array is null.

Answer 2

You are missing following code somewhere and should be getting null pointer exception:

TardyEvenEmorys = new string[22];
