在MVC Razor视图页面中使用string.Format [英] using string.Format in MVC Razor view page

问题描述

我想像这样使用string.Format在Razor视图中渲染图像...

I want to render images in a Razor view using string.Format like this ...

foreach (var p in @Model.Photos)
{                        
    string.Format("<img src='{0}' width='100' alt='{1}' />", p.Path, 
                                 p.AlternateText);                    
}

这显然是错误的，因为在呈现此页面时，本节中没有任何内容.

Something is clearly wrong here, because on rendering this page, I've got nothing inside this section.

推荐答案

string.Format()返回要丢弃的字符串.

string.Format() returns a string, which you're discarding.

您需要将该字符串打印到页面上:

You need to print that string to the page:

@string.Format(...)

请注意，由于这不是语句，因此不应该包含;.

Note that since this isn't a statement, there shouldn't be a ;.

还请注意，使用Razor本身会更好:

Also note that it would be better to use Razor itself:

<img src="@p.Path" width="100" alt="@p.AlternateText" />
