RenderControl不计算响应。写入但是计算<%=%>?

<% Response.Write("foo") %> 但它确实能评估 <%= "bar" %>

<%= %> was shorthand for Response.Write 因为它是在经典的ASP。

... <p><%= "foo" %><% Response.Write("bar"); %></p> ...

呈现控制代码。。。

string output;

using (var mem = new StringWriter())
using (var writer = new XhtmlTextWriter(mem))
{
     page.RenderControl(writer);
     output = mem.GetStringBuilder().ToString();
}

输出。。。

Expected: "<p>foobar</p>" 
Actual: "<p>foo</p>"
