I am using ARCObject SDK in visual studio 2010 and C#. I want to check if a file geodatabase exist in a given folder. i have sued following code to create a personal filegeodatabase or .gdb file .Here is my code:

IWorkspaceFactory workspaceFactory = new FileGDBWorkspaceFactoryClass();

            workspaceFactory.ContainsWorkspace(wrkspcpth, "MyMediaPlayer.gdb");

and now i want if this file exist it not re created.   Any suggestion how to check if the a given geofiledatabase already exist.

IWorkspaceFactory2 wsf = new FileGDBWorkspaceFactoryClass() as IWorkspaceFactory2; 
if (wsf.IsWorkspace(fileGdb)) 
{ 
   ws = wsf.OpenFromFile(fileGdb, 0); 
}

try this ...

public static IWorkspace CreateFileGdbWorkspace(String path)

{

// Instantiate a file geodatabase workspace factory and create a file geodatabase.

// The Create method returns a workspace name object.

Type factoryType = Type.GetTypeFromProgID(

"esriDataSourcesGDB.FileGDBWorkspaceFactory");

IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance

(factoryType);

IWorkspaceName workspaceName = workspaceFactory.Create(path, "MyGDB.gdb", null,

0);

// Cast the workspace name object to the IName interface and open the workspace.

IName name = (IName)workspaceName;

IWorkspace workspace = (IWorkspace)name.Open();

return workspace;

}

Thanks and Regards,
