按MSDN默认值是4096 KB（4 MB）。

As per MSDN the default value is 4096 KB (4 MB).

对于最大的，因为它是一个int数据类型，那么理论上你可以去到2,147,483,647。此外，我想确保你知道，IIS 7使用 maxAllowedContentLength 指定文件上传大小。默认情况下它被设置为3000 30MB左右，并作为一个UINT，它应该从理论上允许一个最大的4,294,967,295

As for the Maximum, since it is an int data type, then theoretically you can go up to 2,147,483,647. Also I wanted to make sure that you are aware that IIS 7 uses maxAllowedContentLength for specifying file upload size. By default it is set to 30000000 around 30MB and being an uint, it should theoretically allow a max of 4,294,967,295
