Asp.net Upload File to Directory Memory Stream

MemoryStream

The MemoryStream creates a stream whose backing store is retentivity. Actually, it represents a pure, in-retentivity stream of data. Retentiveness is much faster when compared to disk or network accesses.

The following section explains :

MemoryStream to FileStream

With MemoryStream, you can act upon the byte[] stored in retentiveness rather than a file or other resource. Utilise a byte[] considering it is a stock-still sized object making it easier for memory allotment and cleanup and holds relatively no overhead, especially since y'all don't need to use the functions of the MemoryStream.

Save Stream to File

C# MemoryStream to a file

using Arrangement; using Arrangement.Text; using System.Windows.Forms; using System.IO; namespace WindowsFormsApplication2 {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         private void button1_Click(object sender, EventArgs e)         {             cord memString = "Retention test cord !!";             // convert string to stream             byte[] buffer = Encoding.ASCII.GetBytes(memString);             MemoryStream ms = new MemoryStream(buffer);             //write to file             FileStream file = new FileStream("d:\\file.txt", FileMode.Create, FileAccess.Write);             ms.WriteTo(file);             file.Close();             ms.Close();         }     } }

Save and load MemoryStream to a file

VB.Internet MemoryStream to a file

Imports Arrangement.IO Imports Organisation.Text Public Grade Form1     Private Sub Button1_Click(ByVal sender Equally System.Object, ByVal east As System.EventArgs) Handles Button1.Click         Dim memString As String = "Retentiveness test string !!!"         ' convert string to stream         Dim buffer As Byte() = Encoding.ASCII.GetBytes(memString)         Dim ms Equally New MemoryStream(buffer)         'write to file         Dim file As New FileStream("d:\file.txt", FileMode.Create, FileAccess.Write)         ms.WriteTo(file)         file.Shut()         ms.Close()     End Sub End Class

Save MemoryStream to a String

The following programme shows how to Read from memorystream to a cord. Steps follows..

StreamWriter sw = new StreamWriter(memoryStream); sw.WriteLine("Your cord to Memoery");

This string is currently saved in the StreamWriters buffer. Flushing the stream will force the string whose backing store is memory (MemoryStream).

How do you become a cord from a MemoryStream

Side by side step is to read this string from memorystream.

ms.Position = 0; StreamReader sr = new StreamReader(ms); string  myStr = sr.ReadToEnd();

Serializing a memorystream object to string

The StreamReader will read from the current position of the MemoryStream which is currently ready at the stop of the string earlier we just wrote to information technology. We take to fix the position to 0 in order to read from the start.

Save MemoryStream to a String - C#

using System; using Organization.Windows.Forms; using System.IO; namespace WindowsFormsApplication1 {     public fractional class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         private void button1_Click(object sender, EventArgs due east)         {             using (MemoryStream ms = new MemoryStream())             {                 StreamWriter sw = new StreamWriter(ms);                 sw.WriteLine("Hello Earth !!");                 sw.Flush();                 ms.Position = 0;                 StreamReader sr = new StreamReader(ms);                 string  myStr = sr.ReadToEnd();                 MessageBox.Evidence(myStr);             }         }     } }

Save MemoryStream to a String - VB.Internet

Imports Arrangement.IO Public Class Form1     Private Sub Button1_Click(ByVal sender Every bit Organization.Object, ByVal due east Equally Organization.EventArgs) Handles Button1.Click         Using ms Equally New MemoryStream()             Dim sw As New StreamWriter(ms)             sw.WriteLine("How-do-you-do World !!")             sw.Flush()             ms.Position = 0             Dim sr As New StreamReader(ms)             Dim myStr As String = sr.ReadToEnd()             MessageBox.Evidence(myStr)         Stop Using     End Sub End Class

There is another methos as well assistance united states to read from Memory stream.

Encoding.ASCII.GetString(ms.ToArray());

C# Source Code

using System; using System.Windows.Forms; using System.IO; namespace WindowsFormsApplication1 {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         individual void button1_Click(object sender, EventArgs due east)         {             using (MemoryStream ms = new MemoryStream())             {                 StreamWriter sw = new StreamWriter(ms);                 sw.WriteLine("Hello World !!!");                 sw.Flush();                 string myStr = Encoding.ASCII.GetString(ms.ToArray ());                 MessageBox.Show(myStr);             }         }     } }

VB.Net Source Code

Imports System.IO Imports System.Text Public Class Form1     Individual Sub Button1_Click(ByVal sender As System.Object, ByVal e As Organisation.EventArgs) Handles Button1.Click Using ms As New MemoryStream()             Dim sw Equally New StreamWriter(ms)             sw.WriteLine("Hello World !!!")             sw.Flush()             Dim myStr As String = Encoding.ASCII.GetString(ms.ToArray())             MessageBox.Show(myStr)         Stop Using     Stop Sub End Course
