推荐答案

您不能使用实例属性（ ClientScript ）或方法（的GetType（） href=\"http://msdn.microsoft.com/en-us/library/aa645766%28v=vs.71%29.aspx\" rel=\"nofollow\">静一（基本上任何实例）。

You cannot use instance properties (ClientScript) or methods (GetType()) inside a static methods (basically anything instance).

删除static关键字，它应该工作：

Drop the static keyword and it should work:

public void SomeMethod()
{
     ClientScript.RegisterSomeScript("Load", 
        "<script>....</script>");
}

评论后编辑：

或者，如果你需要，该方法是在静态类的静态传递Page对象作为参数：

Or if you need that the method is static in a static class pass the Page object as a parameter:

public static class ScriptRegistar
{
    public static void RegisterSomeScript(Page page)
    {
         page.ClientScript.RegisterStartupScript("Load", 
        "<script>.........</script>");
    }
}

使用（页面codebehind内）：

Usage (inside a page codebehind):

public void Page_Load(Object sender, EventArgs e)
{
     ScriptRegistar.RegisterSomeScript(this);
}

边注： ClientScript.RegisterStartupScript 有两个参数：脚本的键，脚本文本，所以没有必要在的GetType （）那里。

Side note: ClientScript.RegisterStartupScript takes two arguments: the key for the script, and script text, so there is no need for the GetType() there.
