String ou des données binaires d'être tronquée. La déclaration a été résilié. Pendant le chargement de profil

Je suis en train d'utiliser l'asp.net Profil de la fonctionnalité de stocker les informations de l'utilisateur. J'ai une image dans les propriétés de profil.

Je suis en utilisant le profil par défaut du fournisseur de données par asp.net dans Visual Studio.

Voici la définition de propriétés dans le web.config

  <properties>
    <add name="FirstName"/>
    <add name="MiddleName"/>
    <add name="LastName"/>
    <add name="ProfileImage" type="System.Byte[]" defaultValue='null'/>
    <add name="MobileNumber"/>
    <add name="TelephoneNumber"/>
  </properties>

C'est le code:

protected void Button1_Click(object sender, EventArgs e)
{
var profile = HttpContext.Current.Profile;
profile.SetPropertyValue("FirstName", TextBox1.Text);
profile.SetPropertyValue("LastName",TextBox3.Text);
profile.SetPropertyValue("MiddleName", TextBox2.Text);
profile.SetPropertyValue("MobileNumber", TextBox4.Text);
profile.SetPropertyValue("TelephoneNumber", TextBox5.Text);
if (IsPostBack)
{
Boolean fileok = false;
String path = Server.MapPath("~/UploadedImages/");
path = System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(path);
if (FileUpload1.HasFile)
{
String fileExtension = System.IO.Path.GetExtension(FileUpload1.FileName).ToLower();
String[] allowedextensions = { ".gif", ".png", ".jpeg", ".jpg" };
for (int i = 0; i < allowedextensions.Length; i++)
{
if (fileExtension == allowedextensions[i])
{
fileok = true;
}
}
}
if (fileok)
{
byte[] userImage = new byte[1025];
try
{
userImage = ReadFully(FileUpload1.PostedFile.InputStream);
}
catch (Exception ex)
{
//exception while getting the file
return;
}
profile.SetPropertyValue("ProfileImage", userImage);
}
else
{
//file not okay type not image
}
}
}
//-------------------------------------------------------------Get The File in Byte Stream ---------------------------------//
public static byte[] ReadFully(Stream input)
{
byte[] buffer = new byte[input.Length];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}

Mais il est en train de jeter exception suivante, même pour 34KB fichier qui ne peut pas être de droite? Suis-je en train de faire quelque chose de mal?
