如何将字典转换为DataTable？(C#)

using System;
using System.Data;

public class Program
{
    public static DataTable ConvertDictionaryToDataTable<TK, TV>(Dictionary<TK, TV> dictionary)
    {
        DataTable dataTable = new DataTable();

        // 创建列
        foreach (var key in dictionary.Keys)
        {
            dataTable.Columns.Add(key.ToString(), typeof(TV));
        }

        // 创建行
        DataRow dataRow = dataTable.NewRow();
        foreach (var kvp in dictionary)
        {
            dataRow[kvp.Key.ToString()] = kvp.Value;
        }
        dataTable.Rows.Add(dataRow);

        return dataTable;
    }

    public static void Main()
    {
        Dictionary<string, int> dictionary = new Dictionary<string, int>();
        dictionary.Add("Key1", 1);
        dictionary.Add("Key2", 2);

        DataTable dataTable = ConvertDictionaryToDataTable(dictionary);

        // 打印DataTable中的数据
        foreach (DataRow row in dataTable.Rows)
        {
            foreach (var item in row.ItemArray)
            {
                Console.Write(item + " ");
            }
            Console.WriteLine();
        }
    }
}
