Editing a file using C# or VB

Dear Microsoft Visual C# 2008 and Microsoft Visual Basic 2008Experts;

I need to edit a .CSV file using the Script Task within SSIS 2008.  The file will be comma delimited (,) or carrot delimited (^), text qualifier is a quote (“), header row delimiter is a line feed (LF) and column names in the first data row.  Searching though the file there is a common pattern of strings that needs replacing; examples inside the square brackets would be [“”)] replaced with [)], [“”.] replaced with [.], [ “,””] replaced with [“,”] and [\r\n] replaced with a blank space.

I have seen examples of .vbs scripts using replacement like;
 if !foo!==ex3 set foo=ex5
or
 If InStr(strLine,""")")> 0 Then
    	strLine = Replace(strLine,""")",")")

I need something to go within the Script Task in SSIS 2008.

I would assume strLine contains characters that need replacing and I would nest the replace-function:
strLine = Replace(Replace(Replace(Replace(strLine, "old1", "new1"), "old2", "new2"), "old3", "new3"), "old4", "new4")

Hi,

You can also use regular expressions to replace text.
Using this patter will find all the required matches you need then you need to just replace them with what you need.
 var replacedString = "";
replacedString  = Regex.Replace(fileContents, @"\[“”\)\]", "[)]");
replacedString  = Regex.Replace(fileContents, @"\[“”\.\]", "[.]"); 
replacedString  = Regex.Replace(fileContents, @"\[ “,””\]", "[“,”]"); 
replacedString  = Regex.Replace(fileContents, @"[\r\n]", " ");

Hope this helps,
Mishu

VB.NET (replace what's in the double quotes with whatever you need, add as many Replace calls as you need:
strLine = strLine.Replace("old1", "new1").Replace("old2", "new2").Replace("old3", "new3") ... .Replace("oldN", "newN")
