请说明您在strFileName中传递的内容？对路径“C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\…doc.xls”的访问被拒绝时出错。@Victor只需传递您有权保存文件的任何位置。像D:\。它看起来像XmlTextWriter xtwWriter=newXMLTextWriter（@“D:\Filename.xml”，Encoding.UTF8）@Victor请告诉我这是否有帮助？在第一行添加3项后；新的错误出现了<代码>状态epilog中的token startelement将导致xml文档无效。@Victor请计算您的“WriteStarElement”和“WriteEndElement”，如果它们不等于，请检查它们。或者请在这里粘贴您的代码
