Validate uploaded file extension

Question

Uploading files works fine but now I\'m trying to validate file extensions and looks like there\'s some interference between FileUpload1 and FileUpload2

Answer 1

are you uploading both files at the same time, or only one at a time? if it is only one at a time, then one of those values is always going to be false.

You are also adding a period in front of your validPhotoFile and validPDFFile, change your code like this.

for (int i = 0; i < validPhotoFile.Length; i++)
{
    if (photoExt == validPhotoFile[i]) // remove the period here it is already in your variables above
    {
        isValidPhotoFile = true;
        break;
    }
}

for (int i = 0; i < validPDFFile.Length; i++)
{
    if (pdfExt == validPDFFile[i]) // remove the period here it is already in your variables above
    {
        isValidPDFFile = true;
        break;
    }
}
