今天练习Razor的逻辑处理。一般会使用下面
1. if
2. else
3. else if
4. switch
下面演示中，Insus.NET分别演示1，2， 4：
xxx.cshtml代码如下：
@{
Layout = null;
string laborDay = "2015-05-01";
string name = "Insus.NET";
string[] colors = { "ff0000", "0000ff", "00ff00" }; //red, blue, green
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
@if (laborDay.IsDateTime())
{
if (laborDay == "2015-05-01")
{
@: The day is labor day.
}
}
<p><br /></p>
@*
@if (name == "Insus.NET")
{
<p>This is my name: @name.</p>
}
else
{
<p>That's not my name.</p>
}
*@
@(name == "Insus.NET" ? string.Format("This is my name: {0}", @name) : "That's not my name")
<p><br /></p>
@foreach (string s in colors)
{
switch (s)
{
case "ff0000":
@: red
break;
case "00ff00":
@: green
break;
case "0000ff":
@:blue
break;
default:
@: black or white
break;
}
}
</div>
</body>
</html>
动画演示(太约12分钟左右)：
上面的练习演示中，其中有颜色写错了，参考上面的代码为准：
