Definition
Important

Gets the current character encoding that the current StreamReader object is using.
public:
virtual property System::Text::Encoding ^ CurrentEncoding { System::Text::Encoding ^ get(); };
public virtual System.Text.Encoding CurrentEncoding { get; }
member this.CurrentEncoding : System.Text.Encoding
Public Overridable ReadOnly Property CurrentEncoding As Encoding
Property Value
The current character encoding used by the current reader. The value can be different after the first call to any Read method of StreamReader, since encoding autodetection is not done until the first call to a Read method.
Examples
The following code example gets the encoding of the specified StreamReader object.
using namespace System;
using namespace System::IO;
using namespace System::Text;
int main()
{
String^ path = "c:\\temp\\MyTest.txt";
try
{
if ( File::Exists( path ) )
{
File::Delete( path );
}
//Use an encoding other than the default (UTF8).
StreamWriter^ sw = gcnew StreamWriter( path,false,gcnew UnicodeEncoding );
try
{
sw->WriteLine( "This" );
sw->WriteLine( "is some text" );
sw->WriteLine( "to test" );
sw->WriteLine( "Reading" );
}
finally
{
delete sw;
}
StreamReader^ sr = gcnew StreamReader( path,true );
try
{
while ( sr->Peek() >= 0 )
{
Console::Write( (Char)sr->Read() );
}
//Test for the encoding after reading, or at least
//after the first read.
Console::WriteLine( "The encoding used was {0}.", sr->CurrentEncoding );
Console::WriteLine();
}
finally
{
delete sr;
}
}
catch ( Exception^ e )
{
Console::WriteLine( "The process failed: {0}", e );
}
}
using System;
using System.IO;
using System.Text;
class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
try
{
if (File.Exists(path))
{
File.Delete(path);
}
//Use an encoding other than the default (UTF8).
using (StreamWriter sw = new StreamWriter(path, false, new UnicodeEncoding()))
{
sw.WriteLine("This");
sw.WriteLine("is some text");
sw.WriteLine("to test");
sw.WriteLine("Reading");
}
using (StreamReader sr = new StreamReader(path, true))
{
while (sr.Peek() >= 0)
{
Console.Write((char)sr.Read());
}
//Test for the encoding after reading, or at least
//after the first read.
Console.WriteLine("The encoding used was {0}.", sr.CurrentEncoding);
Console.WriteLine();
}
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}
}
