在asp.net應用程序中增加上傳文件的最大長度

Question

我有一個用於上傳項目文件的asp.net mvc應用程序。 所有的東西都可以正常工作，但是我有這個問題，我無法上傳長度大於200Mo的文件。 我認爲這是iis配置中的一個問題，我看到很多教程沒有找到解決辦法來增加iis支持的文件的最大長度。

我認爲這是一個障礙，如果我有一個大文件上傳它（> 200mo），我的應用程序將被限制到這個最大長度，但與其他語言如java或php這個問題不存在。

我有兩個Web.config文件：

<?xml version="1.0" encoding="utf-8"?>

我怎樣才能解決這個問題呢？配置解決方案是否存在？

這是解決方案：

在兩個標籤添加

Answer 2

在webconfig添加此，增加的maxRequestLength按您的需求量的
<system.web> <httpRuntime executionTimeout="110" maxRequestLength="20480"/> </system.web>
