Transform a DataTable into Dictionary C#

Question

I want to know how to transform a DataTable into a Dictionary. I did something like this.

using System.Linq;

internal Dictionary GetDict(Da         


        

Answer 1

i prefer this method:

public static List> GetDataTableDictionaryList(DataTable dt)
{
    return dt.AsEnumerable().Select(
        row => dt.Columns.Cast().ToDictionary(
            column => column.ColumnName,
            column => row[column].ToString()
        )).ToList();
}

the reason why is because this code can also deal with Booleans or other data types by calling the ToString method.

Notice this returns a list of dictionaries, you can modify it to a dictionary of dictionaries if you have key for each row.

iterate over a bool column might look like so:

var list = GetDataTableDictionaryList(dt);

foreach (var row in list)
{
    if (row["Selected"].Equals("true", StringComparison.OrdinalIgnoreCase))
    {
        // do something
    }
}
