编程导出的实现方式和代码示例: 以下是使用C#编程语言将DataTable内容导出到CSV文件的示例代码: 代码语言:txt 复制 using System; using System.Data; using System.IO; public class DataTableToCsvExporter { public static void ExportToCsv(DataTable dataTable, string filePath) { using (StreamWriter writer =...
typeof(string));varrow=dt.NewRow();row["Id"]=1;row["Name"]="one";dt.Rows.Add(row);row=dt.NewRow();row["Id"]=2;row["Name"]="two";dt.Rows.Add(row);using (varwriter=newStringWriter())using (varcsv=newCsvWriter(writer,CultureInfo.InvariantCulture))...

public void ExportDataGridToCSV(DataTable dt) { string strFile = ""; string path = ""; //File info initialization strFile = "test"; strFile = strFile + DateTime.Now.ToString("yyyyMMddhhmmss"); strFile = strFile + ".csv";
According to your description, if you need to export DataTable to CSV file, you could try some thing like this:Copy static void Main(string[] args) { DataTable dt = new DataTable(); dt.Columns.Add("CustomerId", typeof(int)); dt.Columns.Add("CustomerName", typeof(string)); dt....
