如何在新浏览器ASP.NET? [ ^ ]

根据您更改的要求

只需检查

According to your changed requirement

Just check

try
{
if (File.Exists(filePath))
            {
                FileStream sr = new FileStream(filePath, System.IO.FileMode.Open);
                XmlTextReader xtr = new XmlTextReader(sr);
                 ds.ReadXml(xtr);
            }
            else
            {
                Response.Redirect("errorpage.aspx");
            }
}

应该是

Shouldn''t it be

Response.Redirect("Error.aspx");

1)单击按钮，新建网页(新建. aspx)应该会打开，而前一个则保持打开状态.

1) on a button click, new web page(New.aspx) should open, leaving the previous one opened.

target =''_blank''移至您的按钮.

target =''_blank'' to your button.

ScriptManager.RegisterStartupScript(page,
                typeof(Page),
                "Redirect",
                "window.open('./error.aspx');",
                true);
