本文介绍了用lambda exp连接剃须刀中的特殊字符的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述





我想添加一个特殊字符:在我的剃刀视图中,目前通过lambda表达式绑定



 @ Html.DisplayFor(x => x.StoreProfileAssociation.RegionalManager.Title)





我尝试了什么:



我试过这种方式但抛出异常



@ Html.DisplayFor(string.Format({0} {1},x => x.StoreProfileAssociation.RegionalManager.Title,:)

解决方案

视图下创建名为 DisplayTemplates 的文件夹 - > 共享 - > DisplayTemplates 文件夹



  • 观看次数
    • 分享
      • DisplayTemplates




< br $>


在DisplayTemplates文件夹中创建一个视图 MyFormat.cshtml

写下面的代码在自定义格式的cshtml文件中ing $ / $

 @ model  string  
@ string.Format( {0}:,型号)







然后你的剃须刀为



 @ Html.DisplayFor(model = >  model.PropertyName,  MyFormat





来自显示模板 [ ^ ]


你的问题是:你对 string.Format 的调用的第一个参数是委托实例,这根本没有意义。你需要一些价值,而不是寻找价值的方法;然后格式化的字符串将包含在该对象上调用的 System.Object.ToString()返回的任何内容。

Hi ,

I wanted to add an special character : in my razor view which is currently binded via lambda expression

@Html.DisplayFor(x => x.StoreProfileAssociation.RegionalManager.Title)



What I have tried:

I tried in this way but throws an exception

@Html.DisplayFor(string.Format("{0}{1}", x => x.StoreProfileAssociation.RegionalManager.Title,":")

解决方案

Create a Folder named DisplayTemplates under Views-> Shared -> DisplayTemplates Folder

  • Views
    • Shared
      • DisplayTemplates




Create a view as MyFormat.cshtml inside DisplayTemplates Folder
write the following code in the cshtml file for custom formatting

@model string 
@string.Format("{0}:",Model)




and then your razor as

@Html.DisplayFor(model => model.PropertyName,"MyFormat" )



referred from Display For Templates[^]


Your problem is: first parameter of your call to string.Format is the delegate instance, which makes no sense at all. You need some value instead, not the method to find value; and then the formatted string will include anything returned by System.Object.ToString() called on that object.
