C# -如何从字典创建DataTable？

using System;
using System.Data;

class Program
{
    static void Main()
    {
        // 创建一个字典
        Dictionary<string, object> dictionary = new Dictionary<string, object>();
        dictionary.Add("Name", "John");
        dictionary.Add("Age", 30);
        dictionary.Add("City", "New York");

        // 创建一个空的DataTable对象
        DataTable dataTable = new DataTable();

        // 遍历字典的键，将每个键添加为DataTable的列
        foreach (var key in dictionary.Keys)
        {
            dataTable.Columns.Add(key.ToString());
        }

        // 遍历字典的值，将每个值添加为DataTable的行
        DataRow dataRow = dataTable.NewRow();
        foreach (var key in dictionary.Keys)
        {
            dataRow[key.ToString()] = dictionary[key];
        }
        dataTable.Rows.Add(dataRow);

        // 打印DataTable的内容
        foreach (DataRow row in dataTable.Rows)
        {
            foreach (DataColumn column in dataTable.Columns)
            {
                Console.WriteLine(column.ColumnName + ": " + row[column]);
            }
        }
    }
}
