HttpPostedFile file = Request.Files["uploads"];
 file.SaveAs(path+"/uploads/"+filename);
string data = my.b2s(file_get_contents(path +"/uploads/"+ filename));


ASP.net Web.config裡寫下以下區段

<system.web>
	<httpRuntime  maxRequestLength="102400" executionTimeout="600"/>
</system.web>

maxRequestLength 檔案大小(KB)，預設值4096 KB(4MB)，所以102400KB為100MB
executionTimeout 上傳時間(秒)，600秒為10分鐘

<system.webServer>
	<security>
		<requestFiltering>
			<requestLimits maxAllowedContentLength="104857600" />
		</requestFiltering>
	</security>
</system.webServer>

maxAllowedContentLength 檔案大小(byte)，所以104857600(1024*1024*100)為100MB
