C#实现DataTable转.CSV文件

将DataTable转换成CSV文件是一种常见的转换形式,主要通过遍历Table的每行，再对每行遍历每列，实现对数据的读取，然后用分隔符分隔Table的每个栏位数据，把读取的字符写入到CSV文件中。这里每个栏位之间用逗号分隔，每行用换行符。实现代码如下：

public ExecutionResult DataTableToCsv(System.Data.DataTable vContent, string vOutputFilePath)
        {
            ExecutionResult sResult = new ExecutionResult();
            System.Text.StringBuilder sCsvContent;
            try
            {
                sCsvContent = new System.Text.StringBuilder();
                //栏位
                for (int i = ; i < vContent.Columns.Count; i++)
                {
                    sCsvContent.Append(vContent.Columns[i].ColumnName);
                    sCsvContent.Append(i == vContent.Columns.Count -  ? "\r\n" : ",");
                }
                //数据
                foreach (System.Data.DataRow row in vContent.Rows)
                {
                    for (int i = ; i < vContent.Columns.Count; i++)
                    {
                        sCsvContent.Append(row[i].ToString().Trim());
                        sCsvContent.Append(i == vContent.Columns.Count -  ? "\r\n" : ",");
                    }
                }
                File.WriteAllText(vOutputFilePath, sCsvContent.ToString(), Encoding.UTF8);
                sResult.Status = true;
            }
            catch (Exception ex)
            {
                sResult.Message = ex.Message;
                sResult.Status = false;
            }
            return sResult;
        }
