小编jlv*_*ero的帖子

我试图在VS2008的T4模板中使用PGK.Extensions for VB.NET,我得到:

RemoveAllSpecialCharacters不是字符串的成员..

我的T4标题:

<#@ template language="VB" hostspecific="false" debug="true" inherits="Microsoft.VisualStudio.TextTemplating.VSHost.ModelingTextTransformation" #>
<#@ output extension="vb" #>

<#@ assembly name="PGK.Extensions.dll" #> // the dll is found
<#@ import namespace="StringExtensions" #> //Try with and without namespace

在块代码中使用扩展名:

<#
   Me.WriteLine(item.Name.RemoveAllSpecialCharacters.ToUpper)
#>

RemoveAllSpecialCharacters是PGK.Extensions.dll的字符串扩展方法.

有谁能够帮我？

编辑:

好.它的:

<#@ template language="VBv3.5" ...

但这打破了VS2008插件中的DevArt T4 Editor intellisense和语法高亮.请改用有形T4编辑器.

我正在尝试使用WinDbg和SOS调试用于教育目的的.NET托管代码应用程序.

Module Module1

  Sub Main()

    Console.Read()
    throwExceptionMethod()

  End Sub

  Private Sub throwExceptionMethod()

    Dim localString As String = "bad string"
    If localString = "bad string" Then
      Throw New System.NotSupportedException("Can't process the string.")
    End If

  End Sub

End Module

在调试模式下编译时,我可以看到抛出异常的方法和破坏我的应用程序的本地字符串.

输出!CLRStack命令:

两者之间有什么不同

public static IEnumerable<TSource> Where<TSource>
        (this IEnumerable<TSource> source, Func<TSource, bool> predicate)

和

public static IQueryable<TSource> Where<TSource>
        (this IQueryable<TSource> source, 
         Expression<Func<TSource, bool>> predicate)

两种方法都可以以相同的方式接受lambda表达式.

List<string> fruits =
                new List<string> { "apple", "passionfruit", "banana", "mango", 
                                "orange", "blueberry", "grape", "strawberry" };
IEnumerable<string> query = fruits.Where(fruit => fruit.Length < 6);

为什么委托函数的委托功能和表达存在？我必须要小心吗？
