SSIS 2012 Script Task to Get File Properties

Question

Hello,
I researched on how to grab a file properties such as file size, file modified date, etc and I came across the following
link:
I followed exact steps and when I went to execute the package, I got the following error:
Below is the code:
// C# code
// Fill SSIS variables with file properties
using System;
using System.Data;
using System.IO; // Added to get file properties
using System.Security.Principal; // Added to get file owner
using System.Security.AccessControl; // Added to get file owner
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
namespace ST_cb8dd466d98149fcb2e3852ead6b6a09.csproj
[System.AddIn.AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
#region VSTA generated code
enum ScriptResults
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
#endregion
public void Main()
// Lock SSIS variables
Dts.VariableDispenser.LockForRead("User::FilePath");
Dts.VariableDispenser.LockForWrite("User::FileAttributes");
Dts.VariableDispenser.LockForWrite("User::FileCreationDate");
Dts.VariableDispenser.LockForWrite("User::FileExists");
Dts.VariableDispenser.LockForWrite("User::FileInUse");
Dts.VariableDispenser.LockForWrite("User::FileIsReadOnly");
Dts.VariableDispenser.LockForWrite("User::FileLastAccessedDate");
Dts.VariableDispenser.LockForWrite("User::FileLastModifiedDate");
Dts.VariableDispenser.LockForWrite("User::FileOwner");
Dts.VariableDispenser.LockForWrite("User::FileSize");
// Create a variables 'container' to store variables
Variables vars = null;
// Add variables from the VariableDispenser to the variables 'container'
Dts.VariableDispenser.GetVariables(ref vars);
// Variable for file information
FileInfo fileInfo;
// Fill fileInfo variable with file information
fileInfo = new FileInfo(vars["User::FilePath"].Value.ToString());
// Check if file exists
vars["User::FileExists"].Value = fileInfo.Exists;
// Get the rest of the file properties if the file exists
if (fileInfo.Exists)
// Get file creation date
vars["User::FileCreationDate"].Value = fileInfo.CreationTime;
// Get last modified date
vars["User::FileLastModifiedDate"].Value = fileInfo.LastWriteTime;
// Get last accessed date
vars["User::FileLastAccessedDate"].Value = fileInfo.LastAccessTime;
// Get size of the file in bytes
vars["User::FileSize"].Value = fileInfo.Length;
// Get file attributes
vars["User::FileAttributes"].Value = fileInfo.Attributes.ToString();
vars["User::FileIsReadOnly"].Value = fileInfo.IsReadOnly;
// Check if the file isn't locked by an other process
try
// Try to open the file. If it succeeds, set variable to false and close stream
FileStream fs = new FileStream(vars["User::FilePath"].Value.ToString(), FileMode.Open);
vars["User::FileInUse"].Value = false;
fs.Close();
catch (Exception ex)
// If opening fails, it's probably locked by an other process
vars["User::FileInUse"].Value = true;
// Log actual error to SSIS to be sure
Dts.Events.FireWarning(0, "Get File Properties", ex.Message, string.Empty, 0);
// Get the Windows domain user name of the file owner
FileSecurity fileSecurity = fileInfo.GetAccessControl();
IdentityReference identityReference = fileSecurity.GetOwner(typeof(NTAccount));
vars["User::FileOwner"].Value = identityReference.Value;
// Release the locks
vars.Unlock();
Dts.TaskResult = (int)ScriptResults.Success;
Eventually I am looking to just grab the Modified Date from the Windows Explorer folder and insert into table. Any suggestions? Thank you in advance!

Hi SSISJoost,
I am so glad you responded to this thread. You are absolutely right. I copied the entire code including the project name (guid) and that solved the error problem.
Now, what did you do to get the message box? I added the watch and I could see the values but how do I get these values in a table? If I remember correctly, in your blog, you mentioned something about using derived columns. I am familiar with Derived Columns
but how do I do that? I appreciate your response.
Thank you.

I used a second script task to show all variable values. It has a
MessageBox in it and between all
variables I added a
newline to make it more readable...
But with an Execute SQL Task and parameters you can also put these values in a Table... or you can read the file in a Data Flow Task and add those variables (as metadata) to each record with a Derived Column
