Add double quotes to variable name for MS Deploy code in c#

Its a c# code written in a SSIS script task component.
PS_script + #"""$compname = " "\" + Row.computername"\" +
"$appname =" + Row.applicationname + " $appvalue = " + Row.appvalue +
"";
I am tying the MS deploy and setting params coming from table driven. The above statement throws error as I am not able to pass double quotes in computername param.

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/verbatim
In C#, a literal string with the prefix #, "" will be replaced by ".
Example :
var str = #"$compname = """ + Row.computername + #"""";
If the variable Row.computername has the value SERV01, then the result will be :
$compname = "SERV01"
You can also escape a character with \. Then \" will be replaced by ".
Example :
var str = "$compname = \"" + Row.computername + "\"";
If the variable Row.computername has the value SERV01, then the result will be :
$compname = "SERV01"
In you case, you can also use string.Format to more lisibility :
string.Format(
#" $compname = ""{0}"" $appname = ""{1}"" $appvalue = ""{2}""",
Row.computername, Row.applicationname, Row.appvalue
);
Warning, with SSIS script task, you can't use string interpolation (the literal string prefix $).

editing html string having text and several images using regex

I am new to this forum and hoping to get some help.
I have a an HTML string having text and several base64 images.
I need to loop through all image tags adding a slash / before
the closing tag > so that each image ends with /> and return
a new html string with the changes.
so each
<IMG src="data:image/png;base64,iVBORw0KG....">
should then be
<IMG src="data:image/png;base64,iVBORw0KG...."/>
I am not versed with html and I am wondering how to do it
(using regex?).
Here is some pseudo code:
Function GetSourceImges(Sourcehtml As String) As List(Of String)
Dim listOfImgs As New List(Of String)()
'use regex to find image tags
'Return list of base64 image tags
End Function
For each image in list
insert a slash appropriately
next
Reconstitute a new html string with edited images
Thanks

Map all "IMG" tags using LINQ and use their indexes as an anchor to fix the missing "/" characters. please see my comments inside the code.
Sub Main()
Dim htmlstring As String = "<IMG src=""data:image/png;base64,iVBORw0KG....""> " & vbCrLf _
& "<img src=""data:image/png;base64,iVBORw0KG...."">" & vbCrLf _
& "<p>blahblah</p>" & vbCrLf _
& "<IMG src=""data:image/png;base64,iVBORw0KG...."">" & vbCrLf _
& "<p>blahblah</p>"
' find all indxes of img using regex and lambda exprations '
Dim indexofIMG() As Integer = Regex.Matches(htmlstring, "IMG", RegexOptions.IgnoreCase) _
.Cast(Of Match)().Select(Function(x) x.Index).ToArray()
' check from each index of "IMG" if "/" is missing '
For Each itm As Integer In indexofIMG
Dim counter As Integer = itm
While counter < htmlstring.Length - 1
If htmlstring(counter) = ">" Then
If htmlstring(counter - 1) <> "/" Then
' fix the missing "/" using Insert() method '
htmlstring = htmlstring.Insert(counter, "/")
End If
Exit While
End If
counter += 1
End While
Next
Console.WriteLine(htmlstring)
Console.ReadLine()
End Sub

Surprisingly it works with the console app but doesn't when I view it on a richtextbox as in btnEditHTML method below. The generated pdf has only one red dot and not two.
Can't say why.
I must say you have been very helpfull.

I highly recommend just using AngleSharp to parse the HTML, edit the document if required, and save it again.
There are many posts on here about why trying to parse HTML with regular expressions is a bad idea.
var doc = new HtmlParser().Parse(html);
As you aren't actually changing the HTML content, just fixing up the tags, your should be able to just parse it and save it with no changes to fix the tags.

How to use StrDup in C# [duplicate]

This question already has answers here:
Vb.Net convert StrDup to C#.net
(3 answers)
Closed 7 years ago.
Hello I have a code that use with VB.net:
Public Shared Function GetNextID(ByVal Prefix As String) As String
Dim dt As DataTable = Database.GetDataTable("select * from _NumberGeneration Where Entity = '" & Prefix & "'")
If dt Is Nothing OrElse dt.Rows.Count = 0 Then Return ""
Dim format As String = dt.Rows(0)("Format") & ""
Dim sqlCnt As String = dt.Rows(0)("SQL") & ""
Dim cnt As Int32 = Val(Database.ExecuteScalar(sqlCnt)) + 1 ' 11
Dim RN As String = format.Substring(format.IndexOf("["c), 4) ' [R5]
Dim newRN As String = StrDup(CInt(RN.Substring(2,1), "0"c) ' 00000
newRN = cnt.ToString(newRN) ' String.Format(newRN, cnt) ' 00011
Dim newformat As String = format.Replace(RN, newRN) '"PR"yyMM00011
Return Today.ToString(newformat) ' String.Format(newformat, cnt)
End Function
For the StrDup When I write the code with C# same as code below:
string newRN = new string (int.Parse(RN.Substring(2, 1)),'0');
It show the error.

Use the string constructor with character and count parameters:
string newRN = new string('0', 4);
You could also reference the Microsoft.VisualBasic assembly and call the method via the Strings module, but the alternative above is pretty simple.

.NET & Word - How to Convert PlainText to MergeField in Document

i am using Visual Studio .NET (VB)
So if you have a solution in C#, just go here first (http://converter.telerik.com/)
I have a document with text, and an array of words to replace:
I need to replace the plaintext and substitute with actual mergefield
Dim replacements(,) As String =
New String(,) {{"[firstname]", "$Field.FName"},
{"[lastname]", "$Field.LName"},
{"[addr]", "$Field.Addr.St"},
{"[city]", "$Field.City"}}
Dim dotXLoc "c:/test/result.dotx"
Dim Fileformat As Microsoft.Office.Interop.Word.WdSaveFormat = Word.WdSaveFormat.wdFormatXMLTemplate 'SAVE AS DOT
Dim wordApp As Object = New Microsoft.Office.Interop.Word.Application()
Dim currentDoc As Microsoft.Office.Interop.Word.Document = wordApp.Documents.Open(dotXLoc)
' Get bounds of the array.
Dim bound0 As Integer = replacements.GetUpperBound(0)
' Loop over all elements.
For i As Integer = 0 To bound0
' Get element.
Dim FieldFind As String = replacements(i, 0)
Dim FieldReplace As String = replacements(i, 1)
'<<< CODE HERE TO REPLACE TEXT WITH MERGEFIELD >>>
Next
currentDoc.SaveAs(dotXLoc & " v2.dotx", Fileformat)
currentDoc.Close()
wordApp.Quit()

Here is the end result
Public sub main()
Dim rtfLoc = "c:/temp.rtf"
Dim dotXLoc = "c:/temp.dotx"
Dim Fileformat As Microsoft.Office.Interop.Word.WdSaveFormat = Word.WdSaveFormat.wdFormatXMLTemplate
Dim wordApp As Word.Application = New Microsoft.Office.Interop.Word.Application()
Dim currentDoc As Microsoft.Office.Interop.Word.Document = wordApp.Documents.Open(rtfLoc)
TextToMergeField(currentDoc)
currentDoc.SaveAs(dotXLoc, Fileformat)
currentDoc.Close()
wordApp.Quit()
End Sub
we call TextToMergeField(currentDoc) from the main function
this way we can loop through multiple documents and replace all instances
Private Sub TextToMergeField(ByRef currentdoc As Word.Document)
Dim rng As Word.Range
Dim replacements(,) As String =
New String(,) {{"[firstname]", "$Field.FName"},
{"[lastname]", "$Field.LName"},
{"[addr]", "$Field.Addr.St"},
{"[city]", "$Field.City"}}
Dim bound0 As Integer = replacements.GetUpperBound(0)
currentdoc.Activate()
For i As Integer = 0 To bound0
rng = currentdoc.Range
With rng.Find
.Text = replacements(i, 0)
Do While .Execute(Replace:=WdReplace.wdReplaceOne)
currentdoc.Fields.Add(rng, WdFieldType.wdFieldMergeField, replacements(i, 1))
Loop
End With
Next
End Sub
Hope this helps someone

Using a script task in SSIS with C# language, how to convert a DTS ActiveX script that creates files and then appends the full file names

I'm trying to convert a DTS process to SSIS and I want to convert a DTS script task that creates 3 files (only creates the file if there’s data to write to it) and then appends the full file names to a variable, which is then copied to a global variable. Since I'm new to this I would like a step by step demonstation if possible, Please, Please, Pretty Please help...Thanks. Below is an example of the DTS script that creates two instead of three files:
