如何使用.net数据表为parquet.net创建模式

using Parquet;
using System;
using System.Data;

class Program
{
    static void Main(string[] args)
    {
        // 创建一个.NET数据表对象
        DataTable dataTable = new DataTable("MyTable");

        // 定义数据表的列和数据类型
        DataColumn column1 = new DataColumn("Column1", typeof(int));
        DataColumn column2 = new DataColumn("Column2", typeof(string));
        DataColumn column3 = new DataColumn("Column3", typeof(DateTime));

        // 将列添加到数据表
        dataTable.Columns.Add(column1);
        dataTable.Columns.Add(column2);
        dataTable.Columns.Add(column3);

        // 创建Parquet文件的模式
        SchemaBuilder schemaBuilder = new SchemaBuilder();
        foreach (DataColumn column in dataTable.Columns)
        {
            schemaBuilder.AddColumn(column.ColumnName, column.DataType);
        }
        Schema schema = schemaBuilder.Build();

        // 创建Parquet文件
        using (ParquetWriter writer = new ParquetWriter("path/to/parquet/file.parquet", schema))
        {
            // 可选：设置其他属性
            // writer.CompressionMethod = CompressionMethod.Snappy;

            // 写入数据到Parquet文件
            writer.Write(dataTable);
        }

        Console.WriteLine("Parquet file created successfully.");
    }
}
