Hi community,

I am trying to run the below C sharp code in UiPath using invoke code activity. I know the regular C sharp codes do not work in invoke code activity directly, can any one help me in compacting/ making the below code running state using invoke code activity.

 public virtual ActionResult Download()
    {          
        ClientContext ctx = new ClientContext("https://ABC.sharepoint.com");
        SecureString passWord = new SecureString();
        foreach (char c in "Pass@word12".ToCharArray()) passWord.AppendChar(c);
        ctx.Credentials = new SharePointOnlineCredentials("abc@gmail12.com", passWord);
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
        var fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(ctx, "/sites/Test/testdoc.docx");        
        return File(fileInfo.Stream, "application/octet-stream", "testdoc.docx");
    }

Any helps much appreciated

Thanks

Hey @Dhruvi_Arumugam

ClientContext ctx = new ClientContext("https://ABC.sharepoint.com");
SecureString passWord = new SecureString();
foreach (char c in "Pass@word12".ToCharArray()) passWord.AppendChar(c);
ctx.Credentials = new SharePointOnlineCredentials("abc@gmail12.com", passWord);
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(ctx, "/sites/Test/testdoc.docx");

fileInfo will be an out argument in the invoke workflow activity.

Hope this helps

Thanks

Hey @Dhruvi_Arumugam

Did you installed the library and imported in studio ?

Check in your Visual studio using statements section !

Thanks

Hi @Dhruvi_Arumugam ,

You would require to install the Below Package for Resolving Namespace Validation issues I suppose :

or Install the below Dependencies of the Package separately, if not present already by Checking in the Imports Section :

We do have the Sharepoint Activities that should do a Similar Operation as you are trying to perform using the c# Code, you could use it too instead of the Code.

Hi @supermanPunch,

@Dhruvi_Arumugam ,

If you have the Package already Installed, then it shouldn’t give you the Problem of namespaces for your c# code.

Hi,

How about the following?

Microsoft.SharePoint.Client.ClientContext ctx = new Microsoft.SharePoint.Client.ClientContext("https://ABC.sharepoint.com");
System.Security.SecureString passWord = new System.Security.SecureString();
foreach (char c in "Pass@word12".ToCharArray()) passWord.AppendChar(c);
ctx.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials("abc@gmail12.com", passWord);
 System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
var fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(ctx, "/sites/Test/testdoc.docx");        
using(Stream outStream = File.OpenWrite(@"C:\temp\testdoc.docx"))
{
   fileInfo.Stream.CopyTo(outStream);
 }

Hi @Dhruvi_Arumugam,

As @supermanPunch mentioned install that dependencies and use the activity instead of code. It will be very easy to download the files using those activity

  1. Use “Sharepoint Application Scope” activity provide your sharepoint site link and credential eg: “https://ABC.sharepoint.com/Sites/Yoursitename”
  2. Then use “Get File” activity to download the file eg: Item url "Shared Documents/Test/testdoc.docx" and local path "C:\temp\testdoc.docx"

Hi,

Basically, the above code is added just proper namespace to the original code. (I re-wrote code regarding System.Web.Mvc.ActionResult)

We can get information for Microsoft.SharePoint.Client in details in the following document, for example.
