CRM 2011 - How to update each field of each entity using c#

  Hi,

  I want to update all fields of an entity. I check if the field property "IsValidForUpdate = true" and want to insert the new values.

  Contact con = xrm.ContactSet.Where(c => c.ContactId == id).First();
  foreach (FieldItem field in listItem.FieldItems)
  {
      if (field.ToUpdate)
      {
          if (field.Value != null) 
          {
              con[field.InternalName] = field.Value;
          }
          xrm.UpdateObject(con);
      }
  }
  xrm.SaveChanges();

  I got an "Incorrect attribute value type System.String" exception. So I tried to cast the field.Value:

  RetrieveEntityResponse res = (RetrieveEntityResponse)xrm.Execute(req);
  //...
  foreach (var s in res.EntityMetadata.Attributes)
  {
      //...
      TypeAsString = s.AttributeType.ToString();
      //...
  }
  
  //update entity
  con[field.InternalName] = Convert.ChangeType(field.Value, Type.GetType(field.TypeAsString));

  But it won't work, because the Types that I get from CRM 2011 are not C# conform.

  I hope that someone can help me.

  Best regards, Markus
