QC DATA PULLER using C#[^]3

Thank You!

What I have tried:

Using below code i am able to read all fields code.

foreach (IBug thisBug in bugL)
                        {
                            dsbug.Tables[0].Rows.Add(thisBug.ID, thisBug.Summary, thisBug.Status, thisBug.AssignedTo, thisBug.DetectedBy, thisBug.ToString(), thisBug.Priority);
}

In Entities, IBug class has below code.

[DefaultMember("Field")]
    [Guid("2AF970F7-6CCC-4DFB-AA78-08F689481F94")]
    [TypeLibType(4160)]
    public interface IBug : IBaseFieldExMail
    {
        [DispId(0)]
        dynamic this[string FieldName] { get; set; }
        [DispId(20)]
        string AssignedTo { get; set; }
        [DispId(12)]
        dynamic Attachments { get; }
        [DispId(5)]
        bool AutoPost { get; set; }
        [DispId(23)]
        List ChangeLinks { get; }
        [DispId(19)]
        string DetectedBy { get; set; }
        [DispId(13)]
        bool HasAttachment { get; }
        [DispId(22)]
        bool HasChange { get; }
        [DispId(11)]
        dynamic History { get; }
        [DispId(4)]
        dynamic ID { get; }

Using foreach (IBug thisBug in bugL), i am able to read all fields, except dynamic this[string FieldName]. dynamic this["field"] has custom fields, i need to read dynamic this value.

How to read below entity in class file.

dynamic this[string FieldName]

Ask whomever wrote the code to help you. You might want to consider posting a description of an actual problem.

First, you have posted the interface and not class code. Please update the question with the class code.

Second, the "field" you are trying to read is a actually an indexer. You can read about indexers here:MSDN[^]. From the link:

Quote:
Indexers allow instances of a class or struct to be indexed just like arrays. Indexers resemble properties except that their accessors take parameters.

Looking at the code you have posted, here is what I can assume might be done in the class:

C#

static class Program
{
    static void Main(string[] args)
    {

        BugClass classObj = new BugClass();

        classObj.Id = 1;
        classObj.Name = "First";

        int firstId = classObj["Id"];
        string firstName = classObj["Name"];

        Console.Read();
    }
}


public interface IBug
{
    dynamic this[string FieldName] { get; set; }

    int Id { get; set; }

    string Name { get; set; }

}

class BugClass:IBug
{

    public dynamic this[string FieldName]
    {
        get
        {
            return this.GetType().GetProperty(FieldName).GetValue(this);
        }
        set
        {
            this.GetType().GetProperty(FieldName).SetValue(this, value);
        }
    }

    public int Id
    {
        get;
        set;
    }

    public string Name
    {
        get;
        set;
    }
}

Here, dynamic this itself does not really hold anything. It merely is an alternate way to play around with class properties. As long as you are reading all the values from the properties, your code should be fine.
