看到这个：

The difference between Response.Write()and Response.Output.Write()in ASP.NET. The short answer is that the latter gives you String.Format-styleoutput and the former doesn't. The long answer follows.

Response.Write()和Response.Output.Write()在 ASP.NET 中的区别。简短的回答是后者给你String.Format-style输出，而前者没有。长答案如下。

In ASP.NET the Responseobject is of type HttpResponseand when you say Response.Writeyou're really saying (basically) HttpContext.Current.Response.Writeand calling one of the many overloaded Writemethods of HttpResponse.

在ASP.NET的Response对象类型HttpResponse，当你说Response.Write你是真心的（基本）HttpContext.Current.Response.Write和调用的许多重载一个Write方法HttpResponse。

Response.Writethen calls .Write()on it's internal TextWriterobject:

Response.Write然后调用.Write()它的内部TextWriter对象：

public void Write(object obj){ this._writer.Write(obj);} 

HttpResponsealso has a Property called Outputthat is of type, yes, TextWriter, so:

HttpResponse也有一个名为 的属性Output，其类型为，是的TextWriter，因此：

public TextWriter get_Output(){ return this._writer; } 

Which means you can do the Responsewhatever a TextWriterwill let you. Now, TextWriters support a Write()method aka String.Format, so you can do this:

这意味着您可以随心所欲地做Response任何事情TextWriter。现在，TextWriters 支持一种Write()方法 aka String.Format，因此您可以执行以下操作：

Response.Output.Write("Scott is {0} at {1:d}", "cool",DateTime.Now);

But internally, of course, this is happening:

但在内部，当然，这正在发生：

public virtual void Write(string format, params object[] arg)
{ 
this.Write(string.Format(format, arg)); 
}

Nothing, they are synonymous (Response.Writeis simply a shorter way to express the act of writing to the response output).

没什么，它们是同义词（Response.Write只是表达写入响应输出的行为的一种更短的方式）。

If you are curious, the implementation of HttpResponse.Writelooks like this:

如果你好奇，它的实现HttpResponse.Write看起来像这样：

public void Write(string s)
{
    this._writer.Write(s);
}

And the implementation of HttpResponse.Outputis this:

的实现HttpResponse.Output是这样的：

public TextWriter Output
{
    get
    {
        return this._writer;
    }
}

So as you can see, Response.Writeand Response.Output.Writeare truly synonymous expressions.

因此，大家可以看到，Response.Write并且Response.Output.Write是真正的同义表达。

Response.write() don't give formatted output. The latter one allows you to write formatted output.

Response.write() 不提供格式化输出。后一个允许您编写格式化输出。

Response.write - it writes the text stream Response.output.write - it writes the HTTP Output Stream.

Response.write - 它写入文本流 Response.output.write - 它写入 HTTP 输出流。

Response.write()is used to display the normal text and Response.output.write()is used to display the formated text.

Response.write()用于显示普通文本，Response.output.write()用于显示格式化文本。

Here Response.Write():to display only string and you can not display any other data type values like int,date,etc.Conversion(from one data type to another) is not allowed. whereas Response .Output .Write(): you can display any type of data like int, date ,string etc.,by giving index values.

这里 Response.Write(): to display only string and you can not display any other data type values like int,date,etc.Conversion(from one data type to another) is not allowed. 不允许转换（从一种数据类型到另一种）。而 Response .Output .Write()：您可以通过提供索引值来显示任何类型的数据，例如 int、date、string 等。

Here is example:

这是示例：

protected void Button1_Click(object sender, EventArgs e)
    {
       Response.Write ("hi good morning!"+"is it right?");//only strings are allowed        
       Response.Write("Scott is {0} at {1:d}", "cool", DateTime.Now);//this will give error(conversion is not allowed)
       Response.Output.Write("\nhi goood morning!");//works fine
       Response.Output.Write("Jai is {0} on {1:d}", "cool", DateTime.Now);//here the current date will be converted into string and displayed
    }
