Send an Email via CSOM - What dll are needed and where to get them

Question

Ok, so I am no an administrator so i cannot just remote into the box and grab the necessary .dlls

What I want to do is use the Sharepoint mailing system to send an email.

I installed the Nuget Package MicrosoftSharepoint2010 which installed

• Microsoft.SharePoint
• Microsoft.SharePoint.Client
• Microsoft.SharePoint.Client.Runtime
• Microsoft.SharePoint.Linq
• Microsoft.SharePoint.Publishing
• Microsoft.SharePoint.Security
• Microsoft.SharePoint.Taxanomy
• Microsoft.SharePoint.Taxanomy.Intl
• Microsoft.SharePoint.WorkflowActions

I have used this code successfully to read and write to lists..

 Business.Utility.loadConfigurations();
 Uri uri = new Uri(SharePointConnector.sp_site_address);

 using (ClientContext clientContext = new ClientContext(uri))
 {
  //do stuff
 }

However if I use this code to send an email it tells me I need the assembly for Utilities.EmailProperties

 User sendToUser = clientContext.Web.EnsureUser("[email protected]");
 clientContext.Load(sendToUser);
 clientContext.ExecuteQuery();
 string email = Microsoft.SharePoint.Client.Utilities.Utility.GetCurrentUserEmailAddresses(clientContext).Value;
 Microsoft.SharePoint.Client.Utilities.EmailProperties properties = new Microsoft.SharePoint.Client.Utilities.EmailProperties();
 properties.To = new string[] { sendToUser.Email };
 properties.Subject = "subject";
 properties.Body = "body";

 Microsoft.SharePoint.Client.Utilities.Utility.SendEmail(clientContext, properties);
 clientContext.ExecuteQuery();

and If i instead try something like the below I instead get this error

'Could not load file or assembly 'Microsoft.SharePoint.Library, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies.

'

    using (SPSite oSPSite = new SPSite(SharePointConnector.sp_site_address))  //Site collection URL
    {
        using (SPWeb oSPWeb = oSPSite.OpenWeb("DGPA"))  //Subsite URL
        {
            StringDictionary headers = new StringDictionary();

            headers.Add("from", "[email protected]");
            headers.Add("to", "[email protected]");

            headers.Add("subject", "Welcome to the SharePoint");
            headers.Add("fAppendHtmlTag", "True"); //To enable HTML format

            System.Text.StringBuilder strMessage = new System.Text.StringBuilder();
            strMessage.Append("Message from CEO:");

            strMessage.Append("<span style='color:red;'> Make sure you have completed the survey! </span>");
            SPUtility.SendEmail(oSPWeb, headers, strMessage.ToString());

        }
    }

You install by using Manage NuGet packages as shown in below image it refer all the client dlls required

you refer the utilities in class file using Microsoft.SharePoint.Client.Utilities;

copy the below code to send emails and test it will send emails. Make sure you give in house(with in domain) email address not out side emails address

    ClientContext ctxSite = new ClientContext("Siteurl");
    string UserID = "[email protected]";
    string Pwd = "password";

    SecureString _pwd = new SecureString();
    foreach (char c in Pwd.ToCharArray())
    {
        _pwd.AppendChar(c);
    }
     ctxSite.Credentials = new SharePointOnlineCredentials(UserID, _pwd);
    ctxSite.ExecuteQuery();
    var emailp = new EmailProperties();
    emailp.BCC = new List<string> { "[email protected]" };
    emailp.To = new List<string> { "[email protected]" };
    emailp.Body = "<b>Test Email</b>";
    emailp.Subject = "Test subject";
    Utility.SendEmail(ctxSite, emailp);
    ctxSite.ExecuteQuery();
