Question

Here are my two objects

    public class ObjectHeaderBuffer
    {
       public int DataObjectId { get; set; }
       public string FileName { get; set; }
       public int RowCount { get; set; }
       public string Checksum { get; set; }
       public int ReconTarget { get; set; }
    } 

    public class ObjectHeaderAttribute
    {
       public int DataObjectId { get; set; }
       public int AttributeType { get; set; }
       public int AttributeValue { get; set; }

    }

        var ohBuffer = new List<ObjectHeaderBuffer>();
        var ohAttribute = new List<ObjectHeaderAttribute>();

I want to update ohBuffer.ReconTarget with ohAttribute.AttributeValue where ohBuffer.DataObjectId == ohAttribute.DataObjectId

what is linq or lambda of this?

Answer 1

They way i did is:

 foreach (var objectHeaderBuffer in ohBuffer)
        {
            var objectHeaderAttribute = (from c in ohAttribute where c.DataObjectId == objectHeaderBuffer.DataObjectId select c).First();
            objectHeaderBuffer.ReconTarget = objectHeaderAttribute.AttributeValue;
        }
