ASP.NET将图像路径更改为https

我有生成图像路径的代码。问题是我的站点已更改为https，并且图像不再显示，因为图像路径是http。有人能建议我如何将下面的代码更改为https吗

If routes.ContainsKey(m_id) Then
            Dim m_uri As Uri = CurrentNode.Uri
      Dim m_builder As New UriBuilder (m_uri.Scheme,m_uri.Host)
            m_builder.Path=String.Format("/resources/image/gritroutes/gritmaps/{0}.jpg",m_id)
            TitleBar.Text = Property_title + " for " + routes.item(m_id) + " - Council"
            phGritPic.Text = String.Format("<img src='{0}' alt='grit route' style='max-width: 530px;' class='auto' />",m_builder.ToString)
            phGrittingKeyText.Visible = True
        End If

如果routes.ContainsKey（m_id）那么
Dim m_uri As uri=CurrentNode.uri
Dim m_builder作为新的UriBuilder（m_uri.Scheme，m_uri.Host）
m_builder.Path=String.Format（“/resources/image/gritroutes/gritmaps/{0}.jpg”，m_id）
TitleBar.Text=属性_title+“用于”+路线项目（m_id）+“-议会”
phGritPic.Text=String.Format（“，m_builder.ToString）
phgritingkeytext.Visible=True
如果结束

您可以将m_url.Scheme更改为m_uri.SchemeHttps

If routes.ContainsKey(m_id) Then
            Dim m_uri As Uri = CurrentNode.Uri
      Dim m_builder As New UriBuilder (m_uri.SchemeHttps,m_uri.Host)
            m_builder.Path=String.Format("/resources/image/gritroutes/gritmaps/{0}.jpg",m_id)
            TitleBar.Text = Property_title + " for " + routes.item(m_id) + " - Council"
            phGritPic.Text = String.Format("<img src='{0}' alt='grit route' style='max-width: 530px;' class='auto' />",m_builder.ToString)
            phGrittingKeyText.Visible = True
        End If

如果routes.ContainsKey（m_id）那么
Dim m_uri As uri=CurrentNode.uri
将m_生成器作为新的UriBuilder（m_uri.SchemeHttps、m_uri.Host）进行Dim
m_builder.Path=String.Format（“/resources/image/gritroutes/gritmaps/{0}.jpg”，m_id）
TitleBar.Text=属性_title+“用于”+路线项目（m_id）+“-议会”
phGritPic.Text=String.Format（“，m_builder.ToString）
phgritingkeytext.Visible=True
如果结束
