推荐答案

将ScriptMethod属性添加到您的方法中，并将签名更新为以下内容:

Add the ScriptMethod attribute to your method and update the signature to the following:

public string[] HelloWorld(string prefixText, int count)

...并确保大小写匹配.适当地更新您的代码(新的变量名).这是文档所需的签名.

我认为其他一切都很好.

干杯，

...and make sure the case matches. Update your code appropriately as well (new variable name). This is the signature required by the docs.

I think everything else looks okay.

Cheers,
