如何从单列的DataTable转到csv

using System;
using System.Data;
using System.IO;
using System.Text;

public class DataTableToCsvConverter
{
    public static void ConvertToCsv(DataTable dataTable, string csvFilePath)
    {
        // 将DataTable中的数据转换为二维数组
        string[][] data = new string[dataTable.Rows.Count][];
        for (int i = 0; i < dataTable.Rows.Count; i++)
        {
            data[i] = new string[] { dataTable.Rows[i][0].ToString() };
        }

        // 构建csv文件内容
        StringBuilder csvContent = new StringBuilder();
        foreach (string[] row in data)
        {
            csvContent.AppendLine(string.Join(",", row));
        }

        // 将内容写入csv文件
        File.WriteAllText(csvFilePath, csvContent.ToString());
    }
}

// 使用示例
DataTable dataTable = new DataTable();
dataTable.Columns.Add("Column1");
dataTable.Rows.Add("Value1");
dataTable.Rows.Add("Value2");
dataTable.Rows.Add("Value3");

string csvFilePath = "output.csv";
DataTableToCsvConverter.ConvertToCsv(dataTable, csvFilePath);
