Comentarios

This enumeration is used by the connection manager for validation purposes. For example, if the connection is being used to delete a file, and the connection is pointing to a folder, it fails validation. In addition, this enumerator indicates to the connection manager whether ambiguous names are files or folders. For example, "C:\ABC" could be the name of a new folder, or it could be a new file in the C:\ directory. This enumeration indicates if it is a file or folder.

Ejemplos

The following code example creates a package and adds a FILE ConnectionManager. The DTSFileConnectionUsageType enumeration describes the FileUsageType property as being an existing file by specifying the FileExists value.

using Microsoft.SqlServer.Dts.Runtime;

namespace Microsoft.SqlServer.SSIS.Samples
{
    class mySqlServer_Sample
    {
        static void Main(string[] args)
        {
            Package package = new Package();
            ConnectionManager cm_srcDirectory = package.Connections.Add("FILE");
            cm_srcDirectory.Name = "cm_srcDirectory";
            cm_srcDirectory.ConnectionString =  @"C:\MyFTPDirectory\*.*";
            cm_srcDirectory.Properties["FileUsageType"].SetValue(cm_srcDirectory, DTSFileConnectionUsageType.FileExists);
        }
    }
}
