How to collect values for all the keys from a Dictionary<string,object> in a List

Question

I have a Dictionary<string, Data> collection.

My Data class is has multiple members.

public class Data
{
public string docid{get;set;}
public string filename{get; set;}
public string doctype{get;set;}
}

so, each key in the dictionary has a list of values. I want to write the values for all the keys in a csv file.

My csv file will have columns of

• docid
• filename
• doctype

I have been using LINQ2CSV library for writing into csv, but since it accepts a list and a filepath as a parameter, i am not able to collect values for all the keys into a list. please suggest a better way to achieve this .

Answer 1

LINQ2CSV's Write method accepts IEnumerable<T> . Your Values in dictionary are available as an array. You can do:

cc.Write(yourDictionary.Values, "filePath.csv");

There is no need for getting List<Data> from Dictionary Values , but if you still want to create a List<Data> you can do:

List<Data> myList = yourDictionary.Values.ToList();

or

List<Data> myList = new List<Data>(yourDicitionary.Values);

Answer 2

您可以将字典的值复制到列表中：

var list = dictionary.Values.ToList();
