CPConvert() Method
Converts a string in one CodePage to another. This method receives three parameters; a string which is to be converted, the current code page number and the new code page number.
[VisualBasic]
Public Shared Function CPConvert(ByVal nCurrentCodePage As Integer, ByVal nNewCodePage As Integer, ByVal cExpression As String) As String
[C#]
public static string CPConvert(int nCurrentCodePage, int nNewCodePage, string cExpression)
Example
[VisualBasic]
This example converts the string from Windows CP to Mac CP
Dim lcString1 As String = "Kämäl"
Dim lcString2 As String
lcString2 = CPConvert(1252, 10000, lcString1) 'Returns "K?m?l"
Console.WriteLine(lcString2)
Console.WriteLine(lcString1)
[C#]
string MyString = "äää";
VFPToolkit.others.CPConvert(1252, 10000, MyString);//Converts the string from Windows CP to Mac CP
Implementation
[VisualBasic]
Public Shared Function CPConvert(ByVal nCurrentCodePage As Integer, ByVal nNewCodePage As Integer, ByVal cExpression As String) As String
Dim i As Integer = 0
Dim nLength As Integer = cExpression.Length
'Create a current and new array of bytes with the length of the string
Dim aCurr() As Byte = New Byte(nLength) {}
Dim aNew() As Byte = New Byte(nLength) {}
'Fill the current array from the string
For i = 0 To cExpression.Length - 1 Step i + 1
aCurr(i) = Convert.ToByte(cExpression.Chars(i))
Next
'Get the encoding objects for the current and new Code Pages
Dim CurCP As Encoding = Encoding.GetEncoding(nCurrentCodePage)
Dim NewCP As Encoding = Encoding.GetEncoding(nNewCodePage)
'Fill the new array after converting current code page to new code page
aNew = Encoding.Convert(CurCP, NewCP, aCurr)
'We still have bytes so we convert each byte to a char and add it to a string builder
Dim sb As StringBuilder = New StringBuilder()
For i = 0 To cExpression.Length - 1 Step i + 1
sb.Append(Convert.ToChar(aNew(i)))
Next
'Return a string back
Return sb.ToString()
End Function
