Advantages: "Smart and simple"
It can be used as an MVC view engine, or it can be used to write traditional PHP-like web sites, very lightweight.
Grammar recognition
Embedding variables
<a href= "/products/details/@productId" >the product</a>
Expression (parentheses)
<p>your message: @ ("number is:" + number) </p>
code block (curly brackets)
@{
int number = 1;
String message = "number is" + number;
}
@{var myquote = @ "The person said:" "Hello, Today is Monday." ";}
<text> tags
if (i > 0) {
<text>;</text>
}
Smart Difference @
<p>mail[email protected]Telling: @Date .now.</p>
You can explicitly hit @@ 来 escape with another "@" character
Judge
@if (Products. Count = = 0) {
<p>sorry-no products in this category </p>
}else{
<p>we has a products for you!</p>
}
@if (DateTime.Now.Year = = 2010) {
<span>
The date: @DateTime. Now
</span>
}
Cycle
<ul id= "Products" >
@foreach (var p in products) {
<li>@p.name ([email protected]) </li>
}
</ul>
Template
<! DOCTYPE html>
<body>
<div> @RenderSection ("menu", Optional:true) </div>
<div> @RenderBody () </div>
<div> @RenderSection ("Footer", optional:true) </div>
</body>
-----------------------------
@{layoutpage = "sitelayout.cshtml";}
<p>current datetime: @DateTime .now</p>
@section menu{
<ul id= "Sub-menu" >
<li>item1</li>
<li>item2</li>
</ul>
}
@section footer{
<p>this is my custom footer</p>
}
Auxiliary functions
@Html. labelfor (M = m.productid)
@Html. textboxfor (M = m.productid)
@Html. validationmessagefor (M = m.productid)
Creating auxiliary functions
@helper productlisting (list<product> products) {
<ul>
@foreach (var p in products) {
<li>@p.name ([email protected]) </li>
}
</ul>
}
<div> @ProductListing (model.products) </div>
function parameters
@Grid. Render (
Data:Model.products,
TableStyle: "Grid",
HeaderStyle: "Head",
Alternationrowstyle: "Alt",
Columns:Grid.Columns (
Grid.column ("Name", "Product", Style: "Product"),
Grid.column ("Description", format:@ (<i> @item. description</i>),
Grid.column ("Price", Format:@<span>[email protected]</span>)
)
)
Function
@using System.Text;
@functions {
public static ihtmlstring Repeat (int times, func<int, object> template) {
StringBuilder builder = new StringBuilder ();
for (int i = 0; I < times; i++) {
Builder. Append (Template (i));
}
return new htmlstring (builder. ToString ());
}
}
@Repeat (@<li>list item</li>);
@Repeat (@<li>list Item # @item </li>);
Type conversions
var mystringnum = "539";
var mystringbool = "True";
var mystringfloat = "41.432895";
var mystringdec = "10317.425";
var mydatestring = "12/27/2010";
-------------------------------
if (Mystringnum.isint () ==true)
var myintnumber = Mystringnum.asint ();
var MyVar = Mystringbool.asbool ();
var myfloatnum = Mystringfloat.asfloat ();
var mydecnum = Mystringdec.asdecimal ();
var newdate = Mydatestring.asdatetime ();
File
No extension is required to access the cshtml file. such as: ~/gallery/index
cshtml files starting with underscores cannot be run separately (typically as template files, common controls)
Several special files
_init.cshtml
@{
Set the layout page for the whole site
Layoutpage = "_master.cshtml";
}
_start.cshtml
@{
Websecurity.initializedatabaseconnection ("Photogallery", "Userprofiles", "UserId", "Email", true);
}
