Leadtools.ImageOptimization Namespace > ImageOptimizerDirectoryData Class : TotalFolderFilesCount Property




Gets the total number of files in the directory to be optimized.

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property TotalFolderFilesCount As Integer
Visual Basic (Usage)Copy Code
Dim instance As ImageOptimizerDirectoryData
Dim value As Integer
 
value = instance.TotalFolderFilesCount
C# 
public int TotalFolderFilesCount {get;}
Managed Extensions for C++ 
public: __property int get_TotalFolderFilesCount();
C++/CLI 
public:
property int TotalFolderFilesCount {
   int get();
}

Return Value

The total number of files in the directory to be optimized.

Example

This example will optimize all Jpg files found in a specific directory, and save them into a separate folder
