I have these three methods that allow me to get the content from a server:

        ' Get the HTML response from a server
        ' expC1 Url
        Public Function GetXML(ByVal tcUrl As String) As String
            Dim loReq As System.Net.WebRequest
            Dim lcHtml As String
            loReq = System.Net.WebRequest.Create(tcUrl)
            Dim loResponse As System.Net.WebResponse = loReq.GetResponse()
            Dim loStream As Stream = loResponse.GetResponseStream()
            Dim loStreamReader As StreamReader = New StreamReader(loStream)
            lcHtml = loStreamReader.ReadToEnd()
            Return lcHtml
        End Function

        ' Get the HTML response from a server
        ' expC1 Url
        Public Function GetUrl(ByVal tcUrl As String) As String
            Dim lcHTML As String = ""
            Dim loHTTP As System.Net.WebClient = New System.Net.WebClient
            Dim loEncoding As System.Text.Encoding = New System.Text.ASCIIEncoding
            Dim loRequestedHTML() As Byte
            Try
                loRequestedHTML = loHTTP.DownloadData(tcUrl)
                lcHTML = loEncoding.GetString(loRequestedHTML)
            Catch loError As Exception
                lcHTML = loError.Message
            End Try
            Return lcHTML
        End Function

        ' Get the HTML response from a server
        ' expC1 Url
        ' expN1 Timeout
        Public Function GetUrlTimeout(ByVal tcUrl As String, Optional ByVal tnTimeout As Integer = 5000) As String
            Dim lcHTML As String = ""
            Dim lcUrl As New System.Uri(tcUrl)
            Dim loHTTP As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(lcUrl)
            loHTTP.Timeout = tnTimeout
            Try
                Dim loWebResponse As System.Net.WebResponse = loHTTP.GetResponse()
                Dim loStream As System.IO.Stream = loWebResponse.GetResponseStream()
                Dim loString As New System.IO.StreamReader(loStream)
                lcHTML = loString.ReadToEnd()
            Catch loError As Exception
                lcHTML = loError.Message
            End Try
            Return lcHTML
        End Function

They use a different approach in each. I was wondering if there would be one to consider mostly than the others. One is using System.Net.WebRequest, the other one System.Net.WebClient and the last one System.Net.HttpWebRequest. Any feedback?
