How to Connect to and Disconnect from a Host File System

The first step in accessing a host file system is to connect to the file system. You must use HostFileConnection to access the host file system. After you have connected, you can retrieve, modify, and update the information that you want.

Procedure

To connect and disconnect to a Host File System

1. Create a HostFileConnection object, using the connection string that describes the Host system.

2. Open a connection with a call to HostFileConnection.Open.

3. Interact with the host file system as necessary.

4. When you are finished, release the HostFileConnection object with a call to HostfileConnection.Close and HostFileConnection.Dispose.

   Connections are not implicitly released when a HostFileConnection falls out of scope. Therefore, you need to release the object when you are finished using it.

Example

The following very simple code example shows how to use HostFileConnection to open and close a connection.

try  
   {  
      HostFileConnection cn = new HostFileConnection();  
      cn.ConnectionString = cnstring;  
      cn.Open();  
      // Perform tasks here.  
      cn.Close();  
      cn.Dispose();  
   }
