Hello, For some reason I need to save some big strings into user profiles. Because a property with type string has a limit to 400 caracters I decited to try with binary type (PropertyDataType.Binary) that allow a length of 7500. My ideea is to convert the string that I have into binary and save to property.
I create the property using the code :
context = ServerContext.GetContext(elevatedSite);
profileManager = new UserProfileManager(context);
profile = profileManager.GetUserProfile(userLoginName);
Property newProperty = profileManager.Properties.Create(false);
newProperty.Name = "aaa";
newProperty.DisplayName = "aaa";
newProperty.Type = PropertyDataType.Binary;
newProperty.Length = 7500;
newProperty.PrivacyPolicy = PrivacyPolicy.OptIn;
newProperty.DefaultPrivacy = Privacy.Organization;
profileManager.Properties.Add(newProperty);
myProperty = profile["aaa"];
profile.Commit();
The problem is that when I try to provide the value of byte[] type to the property I receive the error "Unable to cast object of type 'System.Byte' to type 'System.String'.". If I try to provide a string value I receive "Invalid Binary Value: Input must match binary byte[] data type." Then my question is how to use this binary type ?
The code that I have :
SPUser user = elevatedWeb.CurrentUser; ServerContext context = ServerContext.GetContext(HttpContext.Current); UserProfileManager profileManager = new UserProfileManager(context); UserProfile profile = GetUserProfile(elevatedSite, currentUserLoginName); UserProfileValueCollection myProperty= profile[PropertyName];
myProperty.Value = StringToBinary(GenerateBigString());
and the functions for test :
private static string GenerateBigString()
{
StringBuilder sb = new StringBuilder();
for (int i = 0; i < 750; i++) sb.Append("0123456789");
return sb.ToString();
}
private static byte[] StringToBinary(string theSource)
{
byte[] thebytes = new byte[7500];
thebytes = System.Text.Encoding.ASCII.GetBytes(theSource);
return thebytes;
}
