我想是导出数据表到的.csv文件。这是我尝试过的,但花费的时间太长:string strFilePath= @"C:\myCSVfile.csv";——public void CreateCSVFile(DataTable dtDataTablesList, string strFilePath){ // Create the CSV file to which grid data will be exported. StreamWriter sw = new StreamWriter(strFilePath, false); //First we will write the headers. int iColCount = dtDataTablesList.Columns.Count; for (int i = 0; i < iColCount; i++) { sw.Write(dtDataTablesList.Columns[i]); if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); // Now write all the rows. foreach (DataRow dr in dtDataTablesList.Rows) { for (int i = 0; i < iColCount; i++) { if (!Convert.IsDBNull(dr[i])) { sw.Write(dr[i].ToString()); } if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); } sw.Close();}有没有其他方法可以更快地做到这一点?预先感谢您的任何建议。
