我正在测试
这个叫做< a href=> https://github.com/parrots/SignatureToimageDotNet" rel=“nofollow” >SignatureToimageDotNet 的类服务,我无法工作。我应该提到,我对 ASP.NET/C# 来说是新来的。 到目前为止,我创建了一个网站在Webmatrix, 并拥有签名捕捉表, 可以将输出的 JSON 恢复到一个页面, 但无法将其转换为 PNG 图像。 我创建了一个 App_ Code 文件夹, 并将签名Toimage.cs 文件放入其中, 但我不知道怎么称呼它 。
我相信这对有ASP.NET/C#经验的人来说是微不足道的, 我希望有人这样做过或能够这样做,
您在创建 App_Code 文件夹时做了正确的事情, 通常人们会错过这部分。 在拨打该类时, ASP. NET Web Pages 的功能与 PHP 类似。 您在 cshtml 页面顶部创建一个代码块, 当页面加载时会执行 :
根据您在请求中所做的其他工作(我需要更多的信息/代码), 我猜您可以开始使用页面顶端剃刀块内的签名图象类:
@{
if (IsPostback) {
var sigToImg = new SignatureToImage();
var signatureImage = sigToImg.SigJsonToImage(signatureJson);
// do something with the image!
}
}
<html>
....
我知道答案是有点空洞的结尾, 但是如果你有更具体的信息, 请问我关于网页或C#如何运作的问题。
