How to Retrieve Data related to diff datatypes from Dynamics 365 Target Entity Using a Plugin

In this blog post, we’ll walk through how to retrieve different types of data from a Microsoft Dynamics 365 entity using a plugin. We'll explore different field types and their corresponding retrieval methods, including:

Single-line and multiple-line text fields
Numeric fields (Integer, Decimal)
Date fields
Entity reference fields (Lookup)
Currency fields
Option Set and Multiselect Option Set fields

Let’s dive right in!

Retrieving Various Data Types in a Plugin

Single-line / Multiple-line Text (String)

 string accountName = targetEntity.Contains("name") && targetEntity["name"] != null ? 
                         targetEntity.GetAttributeValue<string>("name") : null;

Numeric Fields (Integer and Decimal)

Integer Field:

 int? quantity = targetEntity.Contains("quantity") && targetEntity["quantity"] != null ?
                     targetEntity.GetAttributeValue<int?>("quantity") : null;

Decimal Field:

 decimal? price = targetEntity.Contains("price") && targetEntity["price"] != null ?
                     targetEntity.GetAttributeValue<decimal?>("price") : null;

Date Time Fields (Date and Time / Date Only)

 DateTime? createdOn = targetEntity.Contains("createdon") ? 
                          targetEntity.GetAttributeValue<DateTime?>("createdon") : null;

Entity Reference (Lookup) Fields

Retrieve Entity Reference:

 EntityReference owner = targetEntity.Contains("owner") && targetEntity["owner"] != null ? 
                            targetEntity.GetAttributeValue<EntityReference>("owner") : null;

Retrieve Entity Reference Guid:

 Guid? ownerId = targetEntity.Contains("owner") && targetEntity["owner"] != null ? 
                    targetEntity.GetAttributeValue<EntityReference>("owner")?.Id : null;

Retrieve Entity Reference Logical Name:

 string owner_entityname = targetEntity.Contains("owner") && targetEntity["owner"] != null ? 
                              targetEntity.GetAttributeValue<EntityReference>("owner")?.LogicalName : null;

Currency Fields
Retrieve Currency:

 Money revenue = targetEntity.Contains("revenue") && targetEntity["revenue"] != null ?
                    targetEntity.GetAttributeValue<Money>("revenue") : null;

Retrieve Currency Value:

 decimal? revenueValue = targetEntity.Contains("revenue") && targetEntity["revenue"] != null ?
                            targetEntity.GetAttributeValue<Money>("revenue")?.Value : null;

Retrieve Currency Entity Reference:

 EntityReference? currencyE = targetEntity.Contains("revenue") && targetEntity["revenue"] != null ?
                                 targetEntity.GetAttributeValue<Money>("revenue")?.Currency : null;

Retrieve Currency Name:

 string? currencyCode = targetEntity.Contains("revenue") && targetEntity["revenue"] != null ?
                           targetEntity.GetAttributeValue<Money>("revenue")?.Currency?.Name : null;

Option Set (Single Select)

Retrieve Option Set Value:

 OptionSetValue status = targetEntity.Contains("statuscode") && targetEntity["statuscode"] != null ?
                            targetEntity.GetAttributeValue<OptionSetValue>("statuscode") : null;

Retrieve OptionSet Value and Label:

 int? statusValue = targetEntity.Contains("statuscode") && targetEntity["statuscode"] != null ?
                       targetEntity.GetAttributeValue<OptionSetValue>("statuscode")?.Value : null;

 // Option Set & Two Optionset -> Option Set: If you want optionset formatted value/label                                        
 string statusFormattedValue = targetEntity.FormattedValues.Contains("statuscode") ?
                                  targetEntity.FormattedValues["statuscode"] : null;

Multiselect Option Set

Retrieve Multiselect Option Set Values:

  OptionSetValueCollection interests = targetEntity.Contains("interests") && targetEntity["interests"] != null
                     ? targetEntity.GetAttributeValue<OptionSetValueCollection>("interests")
                     : null;

 // Multi Select Optionset -> If you want optionset values
 int[] selectedValues = targetEntity.Contains("interests") && targetEntity["interests"] != null
                     ? targetEntity.GetAttributeValue<OptionSetValueCollection>("interests").Value
                     : null;

Retrieve MultiSelect OptionSet Labels:

 List<string> selectedLabels = new List<string>();
 if (targetEntity.FormattedValues.Contains("interests"))
 {
    string formattedValues = targetEntity.FormattedValues["interests"];
    selectedLabels = formattedValues.Split(',').ToList();
 }
