How to check if the uploaded image file is brokenfake using ASP.NET C#?

I am using FileUpload control on my ASP.NET C# application, for purpose of uploading images file and I want to check if the uploaded image is broken or not.

My application checks the extensions and it works fine, but if I uploads broken image file or fake image file (such as txt file saved as image file) the server accept it.

My question in short is How to prevent that?
