Since you are using a WebBrowser object, I will assume that this is actually a Windows forms question and not an asp.net question. 由于您使用的是WebBrowser对象，我将假设这实际上是一个Windows窗体问题而不是asp.net问题。
You should look at the InvokeScript function of the web browser. 您应该查看Web浏览器的InvokeScript功能。
Let's say your webpage has the following function: 假设您的网页具有以下功能：
WITHOUT PARAMETERS: 没有参数：
<script type="text/javascript">
// Function Without Parameters
function JavaScriptFunctionWithoutParameters() {
outputID.innerHTML = "JavaScript function called!";
}
</script>
You would want to call it the following way: 您可能希望通过以下方式调用它：
this.webBrowser.InvokeScript("JavaScriptFunctionWithoutParameters");
WITH PARAMETERS: 带参数：
<script type="text/javascript">
// Function With Parameters
function Goto(someParameter) {
outputID.innerHTML = someParameter;
}
</script>
You would call it like this: 你会这样称呼它：
object[] param = new object[1];
param [0] = "DM_NEW_OBJECT.ASPX?DM_CAT_ID=2063&DM_PARENT_ID=2217&INPUTSELECTION=&DM_OBJECT_ID=0&PACK_ID=0&CASE_ID=0&mode=0&SITE=Default";
this.webBrowser1.Document.InvokeScript("Goto", param );

In C# you have to do something like this: 在C＃中你必须做这样的事情：
Page.ClientScript.RegisterStartupScript(this.GetType(),"CallMyFunction","MyFunction()",true);
Or this: 或这个：
ClientScript.RegisterStartupScript(GetType(),"hwa","alert('Hello World');",true);
