ASP.NET：将DataTable呈现为字符串（HTML）的最短方法？ [英] ASP.NET: Shortest way to render DataTable to a string (HTML)?

问题描述

将DataTable转换为字符串（格式为HTML）的最短方法是什么？

What is the shortest way to convert a DataTable into a string (formatted in HTML)?

以编程方式绑定到UI控件并呈现到ASP.NET页是不可接受的。不能依赖于ASP.NET页面生命周期。

Programmatically binding to a UI control and rendering to an ASP.NET page is not acceptable. Can't depend on the ASP.NET page lifecycle.

此目的无关紧要，但要满足好奇心：这是为了进行大量DataTable处理的算法中的记录/调试/转储目的。

The purpose of this shouldn't matter, but to satisfy curiosity: This is for logging/debugging/dump purposes in algorithms that do a lot of DataTable processing.

谢谢！

推荐答案

您可以使用ASP.net控件，例如GridView，DataGrid并使用StringWriter将其渲染到StringBuilder中，无需为此使用ASP.net页，这是控制台中的简单示例

You can use the ASP.net controls such as GridView, DataGrid and point them render into StringBuilder using StringWriter, No need to use ASP.net page for this, this is a simple example in Console

class Program
{
    static void Main(string[] args)
    {
        IList<Person> persons = new List<Person>()
            {
               new Person{Id = 1, Name="Test Name 1"},
               new Person{Id = 2, Name="Test Name 2"}
            };

        GridView gridView = new GridView();
        StringBuilder result =  new StringBuilder();
        StringWriter writer = new StringWriter(result);
        HtmlTextWriter htmlWriter = new HtmlTextWriter(writer);
        gridView.DataSource = persons;
        gridView.DataBind();

        gridView.RenderControl(htmlWriter);

        Console.WriteLine(result);
    }


}


class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
}
