  • _"...i have saved image in database in bytes..."_, you do not say which ORM or data access tech you're using but I'd double check that. – Adriano Repetti Apr 18 '19 at 16:18

    i would think rdr["CompanyLogo"] is coming as a string value and when you are trying to cast it to byte[] ..it is erroring out. – Ashok Apr 18 '19 at 16:53
  • You can get the string as a byte[] by using this `Encoding.UTF8.GetBytes(rdr["CompanyLogo"])` Just be sure to use the correct encoding for whatever your source string type is. – Matthew Brubaker Apr 18 '19 at 18:52
