Connecting to an image service

The following code shows how to open an ArcGIS Server connection, search the service, and return the requested image server object:
[C#]
public static IImageServer GetImageServer(string agsUrl, string serviceName)
{
    IImageServer imageServer = null;

    //Set connection propertyset. sample URL: http://host:port/arcgis/services.
    IPropertySet propertySet = new PropertySetClass();
    propertySet.SetProperty("url", agsUrl);

    //Open an AGS connection.
    Type factoryType = Type.GetTypeFromProgID(
        "esriGISClient.AGSServerConnectionFactory");
    IAGSServerConnectionFactory agsFactory = (IAGSServerConnectionFactory)
        Activator.CreateInstance(factoryType);
    IAGSServerConnection agsConnection = agsFactory.Open(propertySet, 0);

    //Get the image server.
    IAGSEnumServerObjectName agsServerObjectNames = agsConnection.ServerObjectNames;
    agsServerObjectNames.Reset();
    IAGSServerObjectName agsServerObjectName = agsServerObjectNames.Next();
    while (agsServerObjectName != null)
    {
        if ((agsServerObjectName.Name.ToLower() == serviceName.ToLower()) && 
            (agsServerObjectName.Type == "ImageServer"))
        {
            IName pName = (IName)agsServerObjectName;
            IAGSServerObject agsServerObject = (IAGSServerObject)pName.Open();
            imageServer = (IImageServer)agsServerObject;
            break;
        }
        agsServerObjectName = agsServerObjectNames.Next();
    }

    //Return the image server object.
    return imageServer;
}
[VB.NET]
Public Shared Function GetImageServer(ByVal agsUrl As String, ByVal serviceName As String) As IImageServer
Dim imageServer As IImageServer = Nothing

'Set connection propertyset. sample URL: http://host:port/arcgis/services.
Dim propSet As IPropertySet = New PropertySet()
propSet.SetProperty("url", agsUrl)

'Open an AGS connection.
Dim factoryType As Type = Type.GetTypeFromProgID("esriGISClient.AGSServerConnectionFactory")
Dim agsFactory As IAGSServerConnectionFactory = Activator.CreateInstance(factoryType)
Dim agsConnection As IAGSServerConnection = agsFactory.Open(propSet, 0)

'Get the image server.
Dim agsServerObjectNames As IAGSEnumServerObjectName = agsConnection.ServerObjectNames
agsServerObjectNames.Reset()
Dim agsServerObjectName As IAGSServerObjectName = agsServerObjectNames.Next()
While (Not agsServerObjectName Is Nothing)
    If ((agsServerObjectName.Name.ToLower() = serviceName.ToLower()) And (agsServerObjectName.Type = "ImageServer")) Then
        Dim pName As IName = CType(agsServerObjectName, IName)
        Dim agsServerObject As IAGSServerObject = CType(pName.Open(), IAGSServerObject)
        imageServer = CType(agsServerObject, IImageServer)
        Exit While
    Else
        agsServerObjectName = agsServerObjectNames.Next()
    End If
End While

'Return the image server object.
Return imageServer
End Function
