Question

i have the following code to return a list of generics that i want to iterate through and as a result generate a comma separated list of values as a string.

public static List<ReportCriteriaItem> GetCurrentSelection(ReportWizardCriteriaType criteriaType)
    {
        return Criteria.CriteriaList.FindAll(delegate(ReportCriteriaItem item) 
                                                { return item.CriteriaType == criteriaType; }
                                            );
    }

here is the definition for ReportCriteriaItem – the object i make a generic list out of… i think this is the key here, to get its “id” field into a CSV:

public class ReportCriteriaItem
{
    [System.Xml.Serialization.XmlAttribute("id")]
    public string Id { get; set; }

    [System.Xml.Serialization.XmlAttribute("name")]
    public string Name { get; set; }

    [System.Xml.Serialization.XmlAttribute("value")]
    public string Value { get; set; }

    [System.Xml.Serialization.XmlAttribute("type")]
    public ReportWizardCriteriaType CriteriaType { get; set; }

    public ReportCriteriaItem() { }
    public ReportCriteriaItem(ReportWizardCriteriaType criteriaType, string id, string name, string value)
    {
        this.Id = id;
        this.Name = name;
        this.Value = value;
        this.CriteriaType = criteriaType;
    }
}

can i use a for each loop to do this?

Answer 1

string list = "";
foreach (ReportCriteriaItem item in GetCurrentSelection(...)) {
    if (!string.IsNullOrEmpty(list)) list += ",";
    list += item.???;
}
// do something with the list.
