I want to get a substring between <body> to </body>

Dim Files As String() = System.IO.Directory.GetFiles("c:\temp\temp1")
            Dim readpages As New ReadingPages()
            For Each sFile As String In Files
                If readpages.IsaspxFile(sFile) Then
                    Dim fileCont As String = System.IO.File.ReadAllText(sFile)
                    'it found something
                    If fileCont.Contains("<body>") = True Then
                     'I want to read the contents from <body> to </body>
                    End If
                End If
               
            Next

Try:
...

        If fileCont.Contains("<body>") = True Then

            Dim startOffset = fileCont.IndexOf("<body>") + 5
            Dim endOffset = fileCont.IndexOf("</body>")

            Dim body As String = fileCont.Substring(startOffset, endOffset - startOffset)
            Debug.WriteLine(body)

        End If
...

See my answer at:

It seems to be a duplicate question here. Any way my answer compared to Carl's and your original code has the following improvements:
1) Get Files method only retrieves aspx files: (System.IO.Directory.GetFiles("c:\temp\temp1", "*.aspx")
)
2) The body tag is only searched once using index. (No need for fileCont.Contains)

why don't you try with
String.Split(String[],StringOptions)

Open in new window

method ?

may be like this...
String [] sepraters=new String [] {"<body>","</body>"};

String HTML=System.IO.ReadAllText("file");
var values=HTML.split(sepraters,StringSplitOptions.RemoveEmptyEntries);
// values[0] = will be first part before <body>
// values[1] = middle part between <body>,</body>
// values[2] = rest of string till end
