AmazonMetaData Unable to cast object of type System.String

Unable to cast object of type 'System.String' to type 'System.Object[]'

here is the code:

string str = MFI.Helpers.Helpers.AmazonS3ImageURLGet(userType, id, pictureFile);
AmazonMetaData amazonMetaData;
if (MFI.Helpers.Helpers.processingImages.GetObject(str) != null)
{
//amazonMetaData = (AmazonMetaData)((object[])MFI.Helpers.Helpers.processingImages.GetObject(str))[0];
amazonMetaData = (AmazonMetaData)((object[])MFI.Helpers.Helpers.processingImages.GetObject(str))[0];
}

error in amazonMetaData = (AmazonMetaData)((object[])MFI.Helpers.Helpers.processingImages.GetObject(str))[0];

how to solve??

Above line returns a string value and you trying to explicit convert to byte[] which is not possible. Please use string varibale only..
