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.
Пример
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 System;
using System.Collections.Generic;
using System.Text;
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);
}
}
}
