Parameters

pathToMatch
String

The path of the page to match.

usernameToMatch
String

Returns

PersonalizationStateInfoCollection

A PersonalizationStateInfoCollection that contains per-user personalization state information.

Exceptions

ArgumentException

pathToMatch or usernameToMatch before or after trimming is an empty string ("").

-or-

The provider for a personalization provider defined in configuration is not of the correct type.

-or-

The length of the string of any parameter is greater than 256 characters.

ConfigurationErrorsException

A configuration exception occurred while attempting to create and initialize an instance of one of the configured personalization providers.

-or-

The default personalization provider defined in configuration could not be found.

Examples

The following code example demonstrates how to use the FindUserState method. The complete example can be found in the PersonalizationAdministration class overview topic.

Important

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

protected void Button1_Click(object sender, EventArgs e)
{
    if (TextBox3.Text != null)
    {
        PersonalizationStateInfoCollection findresult;
      findresult = PersonalizationAdministration.FindUserState(null, TextBox3.Text);
      if (findresult.Count != 0)
      {
          Label4.Text = findresult.Count + "  user(s) found";
          Label4.Visible = true;
      }
      else
      {
          Label4.Text = "No users found.";
          Label4.Visible = true;
      }
    }
  else
  {
      Label4.Text = "You must enter a user name to find.";
  }

}

Remarks

This method returns a collection of UserPersonalizationStateInfo instances where the pathToMatch parameter value matches the path of a page, and usernameToMatch matches a user name that has personalization data associated with that page. The collection contains only UserPersonalizationStateInfo instances.

This method passes parameter wildcard characters to the underlying personalization provider, so how the data store handles these characters depends on how the provider handles characters such as an asterisk (*), a percent symbol (%), or an underscore (_).

Normally, for SQL-compliant data stores, you can perform a wildcard search on a partial path with the wildcard character appearing at the beginning, the end, or the middle of the search string text in the PathToMatch property. For example, to find all paths that start with "~/vdir", the PathToMatch property would be set to "~/vdir%".

Likewise, a wildcard search on a partial user name could have the wildcard character appear at any point in the text string of the UsernameToMatch property. For example, to find all user names that start with "John", the UsernameToMatch property would look like "John%".

Using the default personalization provider, the PersonalizationStateInfo-derived objects are returned in alphabetical order, and sorted by a combination of path and user name in ascending order. The ordering of the objects in the collection is determined by the provider.

Both pathToMatch and usernameToMatch can be null. The usernameToMatch parameter can have commas (,) because some data stores, such as those running Microsoft SQL Server, allow commas as wildcard characters.

Both pathToMatch and usernameToMatch can be null. The usernameToMatch parameter can have commas (,) because some data stores, such as those running Microsoft SQL Server, allow commas as wildcard characters.

The data returned is constrained by pageIndex and pageSize, where pageIndex controls which records to return and pageSize controls the number of records to return. For example, if pageIndex was set to 0 and pageSize was set to 25, the data returned would be the first 25 entries. If pageIndex was set to 1 and pageSize was set to 25, the data returned would be entries 26 to 50. The totalRecords parameter returns the total number of records that are available.
