how to call a c++ function with wchar_t[] parameter

[Akademos]

You're right, what a stupidy of mine.
This is the correct code:

[ DllImport( "..\\mydll.dll", CharSet=CharSet.Unicode ) ]
    internal static extern bool GetDatabaseInfo( uint uiBuffCnt,
                                                 string sDataSource,
                                                 string sCatalog,
                                                 string sUsername,
                                                 string sPassword
                                               );
                                               
//----------------------------------------------------------------------

		private void Page_Load(object sender, System.EventArgs e)
		{
		  
      string sDataSource = new string( ' ', 1024 );
      string sCatalog = new string( ' ', 1024 );
      string sUsername = new string( ' ', 1024 );
      string sPassword = new string( ' ', 1024 );
      try
      { 
        //sDataSource = sCatalog = sUsername = sPassword = "";         
        GetDatabaseInfo( 1024, m_sDataSource,m_sCatalog,m_sUsername,m_sPassword );
     }

But now I've go the problem that the returning strings a filled with '\0' behind the text when the given length is greater than the actual length.
Now i want to trime the returning string to a fitting size. How can I do that?

Thanks in Advance
