asp.net mvc 4 - upload csv file to blob through c# .net and delete it after entering the data into database -

how can upload .csv file blob , read back-end , delete after data entered database?

as new this,i don't have knowledge of it. had gone through on azure website , tried code doesn't works me.

thanks in advance.

first create container in azure , accountname , access key ur blob storage.

follow link : http://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-blobs-20/

than in visual studio create class file , follow code given below :

public class blobstorageservice {     public cloudblobcontainer getcloudblobcontainer()     {         cloudstorageaccount storageaccount = cloudstorageaccount.parse(system.web.configuration.webconfigurationmanager.appsettings["blobsetting"]);         cloudblobclient blobclient = storageaccount.createcloudblobclient();         cloudblobcontainer blobcontainer = blobclient.getcontainerreference("mycontainer");                     if (blobcontainer.createifnotexists())         {             blobcontainer.setpermissions(new blobcontainerpermissions { publicaccess = blobcontainerpublicaccesstype.blob });         }         return blobcontainer;     }      public string getreaddata(string filename)     {         // retrieve storage account connection string.         cloudstorageaccount storageaccount = cloudstorageaccount.parse(system.web.configuration.webconfigurationmanager.appsettings["blobsetting"]);          // create blob client.         cloudblobclient blobclient = storageaccount.createcloudblobclient();          // retrieve reference created container.         cloudblobcontainer container = blobclient.getcontainerreference("mycontainer");          // retrieve reference blob named "myblob.csv"         cloudblockblob blockblob2 = container.getblockblobreference(filename);          string text;         using (var memorystream = new memorystream())         {             blockblob2.downloadtostream(memorystream);             text = system.text.encoding.utf8.getstring(memorystream.toarray());         }          return text;     } } 

controller :

[httppost] public actionresult uploaddevicestoregister11(httppostedfilebase userdetailcsvfile) {     blobstorageservice df = new blobstorageservice();      if (userdetailcsvfile.contentlength > 0)     {         //to upload file on blob         cloudblobcontainer blobcontainer = df.getcloudblobcontainer();         cloudblockblob blob = blobcontainer.getblockblobreference(userdetailcsvfile.filename);         blob.uploadfromstream(userdetailcsvfile.inputstream);          //to read file blob         blobcontainerread = df.getreaddata(userdetailcsvfile.filename);     }      return view(); }   

hope helps.
