c# - How to check if Azure Blob file Exists or Not -

-

i want check particular file exist in azure blob storage. possible check specifying it's file name? each time got file not found error.

this extension method should you:

public static class blobextensions {     public static bool exists(this cloudblob blob)     {         try         {             blob.fetchattributes();             return true;         }         catch (storageclientexception e)         {             if (e.errorcode == storageerrorcode.resourcenotfound)             {                 return false;             }             else             {                 throw;             }         }     } }

usage:

static void main(string[] args) {     var blob = cloudstorageaccount.developmentstorageaccount         .createcloudblobclient().getblobreference(args[0]);     // or cloudstorageaccount.parse("<your connection string>")      if (blob.exists())     {         console.writeline("the blob exists!");     }     else     {         console.writeline("the blob doesn't exist.");     } }
