Dynamics CRM 365 Error 'The Given Key is not present in dictionary'

By -


As a Dynamics CRM developer we always come across the error saying that 'The Given Key is not present in dictionary'.

The reason we receive this error message because of below issues:-

When we try to get the attribute value from Entity object without checking the attribute.

String AccountNumber=objAccount["accountnumber"];  
The above line will throw error if ObjAccount doesn't contains this attributes. 

TO fix this we should always check attributes in Entity object then get the value.

Resolution:

if(objAccount.attributes.contains("accountnumber"))
String AccountNumber=objAccount["accountnumber"];
          
We can also use below code which will return null if attribute is not present in Entity object.
string AccountNumber=objAccount.GetAtrributeValue<String>("accountnumber");

Happy CRMing!

As Microsoft Dynamics developer, We came across this error regularly in our day to day life. Problem Description :-  "Object reference not set to an instance of an object" There could be multiple reason we come across this issue. However below are few things which can be looked at to fix this issue and save your time. Entity Attribute/Field does not contains data or the value is null. Say you are trying to get FirstName from Lead Entity attribute and splitting the value into two string based on some parameter. string[] strArray=objLead["firstname"].split(','); This particulat line of code will throw Object Reference error if FirstName is null.
