How to Validate Image Files in C#

There are a surprisingly large number of viable image formats in use today — which makes validating unique image uploads a tall task for any application. Thankfully, using the code below, you can easily validate dozens of image formats (including the most common formats, such as PNG, JPG, Gif, etc.) in a single, comprehensive operation.

To take advantage of this API with C# code examples, first use the following command to get the client SDK installed:

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 3.4.2

Then copy & paste from the ready-to-run code below to structure your API call:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;

namespace Example
{
    public class ValidateDocumentImageValidationExample
    {
        public void main()
        {
            // Configure API key authorization: Apikey
            Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");

            var apiInstance = new ValidateDocumentApi();
            var inputFile = new System.IO.FileStream("C:\\temp\\inputfile", System.IO.FileMode.Open); // System.IO.Stream | Input file to perform the operation on.

            try
            {
                // Validate an Image File
                DocumentValidationResult result = apiInstance.ValidateDocumentImageValidation(inputFile);
                Debug.WriteLine(result);
            }
            catch (Exception e)
            {
                Debug.Print("Exception when calling ValidateDocumentApi.ValidateDocumentImageValidation: " + e.Message );
            }
        }
    }
}
