Question

I created a datatable with two column and four rows. I am trying to retrieve information from the row by linq based on the information I provide in the query statement for one column, but I get nothing in console.write statement.

    var super =
        from lang in JapanesePhrases.AsEnumerable()
        where lang.Field<string>("Meaning") == "Song of Truth"
        select lang.Field<string>("Phrase");

    foreach (string item in super)
    {
         Console.Write(item + "\n");
    }

Answer 1

i tried now this code:

    var table = new DataTable();
    table.Columns.Add("Meaning");
    table.Columns.Add("Phrase");

    for (int i = 0; i < 5; i++)
    {
        var row = table.NewRow();
        row["Meaning"] = "Meaning"+i;
        row["Phrase"] = "Phrase"+i;
        table.Rows.Add(row);
    }

    var super = from lang in table.AsEnumerable()
                where lang.Field<string>("Meaning") == "Meaning1" 
                select lang.Field<string>("Phrase");

    foreach (string item in super)
    {
        Console.Write(item + "\n");
    }

    Console.ReadLine();

running seamlessly.

i should check data in datatable.
