当我上传小文件时它工作正常，当我上传大文件时它会出现错误。

错误:" Maximum request length exceeded "

请告诉我如何解决这个问题

在sharepoint 2013中使用托管客户端对象模型上传文件

你可以在SharePoint中这样定义最大请求长度:https://blogs.technet.microsoft.com/sammykailini/2013/11/06/how-to-increase-the-maximum-upload-size-in-sharepoint-2013/

在中央管理>应用程序管理>管理Web应用程序>选择所需的Web应用程序并单击功能区上的常规设置

web。像这样编辑httpRuntime节点(对于2GB文件和无限执行):
