Coderush 插件未生成正确的 try catch end try 块
我们创建了一个小插件来添加 xml 注释块并为函数创建 try-catch。 (我们只需将其添加到我们编写的每个函数中) 但在最新的 devexpress 更新中,我遇到了以下代码的问题。
Private Sub cpAddComment_Apply(ByVal sender As System.Object, ByVal ea As DevExpress.CodeRush.Core.ApplyContentEventArgs) Handles cpAddXMLCommentAndTryCatch.Apply
' create elementbuilder and add current code to it
Dim objMethod As New Method
objMethod = objOldMethod.Clone()
objElementBuilder.AddStatement(Nothing, objMethod)
' add try
Dim objTry As DevExpress.CodeRush.StructuralParser.Try = objElementBuilder.AddTry(objMethod)
Dim objCatch As DevExpress.CodeRush.StructuralParser.Catch = objElementBuilder.AddCatch(objMethod, "Exception", "ex")
' add exception
Dim strErrorString As String = """Error in " + objMethod.Location + """, ex"
Dim objThrow As New DevExpress.CodeRush.StructuralParser.Throw
Dim objException As New DevExpress.CodeRush.StructuralParser.TypeReferenceExpression("Exception")
Dim objExceptionString As New DevExpress.CodeRush.StructuralParser.PrimitiveExpression(strErrorString)
Dim objNewException As New DevExpress.CodeRush.StructuralParser.ObjectCreationExpression(objException)
objNewException.AddArgument(objExceptionString)
objThrow.Expression = objNewException
'objThrow.AddFooter(" ") 'This isnt working either
objElementBuilder.AddThrow(objCatch, objThrow)
' substitute code
Dim newCode As String = objElementBuilder.GenerateCode()
ea.TextDocument.Replace(objOldMethod.Range, newCode, "Update Method", True)
end sub
它没有生成正确的 Try-catch 块,而是生成以下错误代码:
Try
Catch ex As Exception
Throw New Exception("Error in test", ex)End Try
奇怪的是,以下代码似乎可以工作(其代码大致相同,但事件处理程序显示消息框而不是异常)
If not CodeRush.Language.ActiveExtension.DotNetLanguageType = DotNetLanguageType.CSharp Then
Dim objExceptionString As New DevExpress.CodeRush.StructuralParser.PrimitiveExpression("Messagebox.Show(" + strErrorString + ")" + vbCrLf)
objElementBuilder.AddStatement(objCatch, objExceptionString)
Else
此问题存在于 Vb 中。 Net,但在 C# 中括号放置正确。
We've created a little plugin to add a block of xml comment and create a try-catch to a function. (we simply add this to each and every function we write)
But with the latest devexpress update I'm having a problem with the following code.
Private Sub cpAddComment_Apply(ByVal sender As System.Object, ByVal ea As DevExpress.CodeRush.Core.ApplyContentEventArgs) Handles cpAddXMLCommentAndTryCatch.Apply
' create elementbuilder and add current code to it
Dim objMethod As New Method
objMethod = objOldMethod.Clone()
objElementBuilder.AddStatement(Nothing, objMethod)
' add try
Dim objTry As DevExpress.CodeRush.StructuralParser.Try = objElementBuilder.AddTry(objMethod)
Dim objCatch As DevExpress.CodeRush.StructuralParser.Catch = objElementBuilder.AddCatch(objMethod, "Exception", "ex")
' add exception
Dim strErrorString As String = """Error in " + objMethod.Location + """, ex"
Dim objThrow As New DevExpress.CodeRush.StructuralParser.Throw
Dim objException As New DevExpress.CodeRush.StructuralParser.TypeReferenceExpression("Exception")
Dim objExceptionString As New DevExpress.CodeRush.StructuralParser.PrimitiveExpression(strErrorString)
Dim objNewException As New DevExpress.CodeRush.StructuralParser.ObjectCreationExpression(objException)
objNewException.AddArgument(objExceptionString)
objThrow.Expression = objNewException
'objThrow.AddFooter(" ") 'This isnt working either
objElementBuilder.AddThrow(objCatch, objThrow)
' substitute code
Dim newCode As String = objElementBuilder.GenerateCode()
ea.TextDocument.Replace(objOldMethod.Range, newCode, "Update Method", True)
end sub
Instead of generating a correct Try-catch block it generates the following incorrect code:
Try
Catch ex As Exception
Throw New Exception("Error in test", ex)End Try
Strangely enough the following code seems to work(its about the same code but then for event handlers to show a messagebox instead of an exception)
If not CodeRush.Language.ActiveExtension.DotNetLanguageType = DotNetLanguageType.CSharp Then
Dim objExceptionString As New DevExpress.CodeRush.StructuralParser.PrimitiveExpression("Messagebox.Show(" + strErrorString + ")" + vbCrLf)
objElementBuilder.AddStatement(objCatch, objExceptionString)
Else
This problem exists in Vb.Net but in C# the brackets are correctly placed.

这将在 Visual Basic 中正确生成 try/catch 块。
I have reproduced your issue and registered it in DevExpress Support Center. You are welcome to track its status here. Once it is fixed, you can request a build containing the fix from the Support Team at support @ devexpress.com. For now, as a work-around, you can replace this line of code:
into this:
This will generate the try/catch block correctly in Visual Basic.
