    I have written a plugin to create a contact with same name of lead(fullname) onclick of ribbon button(on lead form)... and its working fine.
    Now i want to keep a condition that the contact should be created only if there is no record with that name.. if there is already a contact record with the name then it should throw an error.. How do i add this to the below code  

      if (entity.LogicalName == "lead")
                {
                    Entity resultset = service.Retrieve("lead", entity.Id, new ColumnSet(new String[] { "new_option","fullname" }));
                   
                    if (Convert.ToInt32(resultset.Attributes.Contains("new_option") )==1)
                    {
                        Entity Contact = new Entity("contact");

                        Contact["lastname"] = resultset["fullname"];
                       
                        if (context.OutputParameters.Contains("id"))
                        {
                            Guid ids = new Guid(context.OutputParameters["id"].ToString());
                            
                        }
                        service.Create(Contact);

    Hi,

    Try the following code:

    if (entity.LogicalName == "lead")
{
	Entity resultset = service.Retrieve("lead", entity.Id, new ColumnSet(new String[] { "new_option","fullname" }));
   
	if (Convert.ToInt32(resultset.Attributes.Contains("new_option") )==1)
	{
		if (resultset.Attributes.Contains("fullname"))
		{
			QueryExpression _query = new QueryExpression
			{
				EntityName = "contact",
				ColumnSet = new ColumnSet(true),
				Criteria =
				{
					FilterOperator = LogicalOperator.And,
					Conditions =
					{
						new ConditionExpression
						{
							AttributeName="fullname",
							Operator=ConditionOperator.Equal,
							Values=resultset["fullname"]

						}
					}
				}

			};

			EntityCollection _contacts = service.RetrieveMultiple(_Query);

			if (_contacts.Entities.Count > 0)
			{
				throw InvalidPluginException("Contact already exists with the same name");
			}
		
			Entity Contact = new Entity("contact");

			Contact["lastname"] = resultset["fullname"];
		   
			if (context.OutputParameters.Contains("id"))
			{
				Guid ids = new Guid(context.OutputParameters["id"].ToString());
				
			}
			service.Create(Contact);
		}
	}
}

    Hi,

    Could you try with .ToString()

    Conditions =
					{
						new ConditionExpression
						{
							AttributeName="fullname",
							Operator=ConditionOperator.Equal,
							Values=resultset["fullname"].ToString()

						}
					}

    Hi amy,

    Try the code below , it works fine.Pls try add your values to your condition. Also i suggest you to use Linq in Crm. It is better using early bound and easy to write.


    QueryExpression expression = new QueryExpression();
    expression.EntityName = "contact";
    expression.ColumnSet = new ColumnSet(true);
    ConditionExpression condition = new ConditionExpression();
    condition.AttributeName = "fullname";
    condition.Operator = ConditionOperator.Equal;
    condition.Values.Add(Convert.ToString(resultset["fullname"]));
    expression.Criteria.AddCondition(condition);
    EntityCollection _contacts = service.RetrieveMultiple(expression);

    Mark as answered if it is helpful for you.
