Vor einer ganzen Weile habe ich mal die StringWriter-Klasse empfohlen.
Die StringWriter-Klasse nutzt intern UTF-16, wodurch zum Beispiel bei der Xml-Serialisierung von Klassen auch das Ergebnis in UTF-16 vorliegt. Dies ist nicht zwangsläufig gewünscht, bei mir hat dadurch ein Backend-Service gestreikt.
Um trotzdem den StringWriter weiter zu verwenden, muss man sich eine eigene Klasse schreiben, welche von der StringWriter ableitet und das Encoding-Property überschreibt:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 | using System;using System.IO;using System.Text;namespace Utilities.IO{ /// <summary> /// A simple class derived from StringWriter, but which allows /// the user to select which Encoding is used. This is most /// likely to be used with XmlTextWriter, which uses the Encoding /// property to determine which encoding to specify in the XML. /// </summary> public class StringWriterWithEncoding : StringWriter { private Encoding _encoding; /// <summary> /// Initializes a new instance of the StringWriterWithEncoding class /// with the specified encoding. /// </summary> /// <param name = "encoding">The encoding to report.</param> public StringWriterWithEncoding(Encoding encoding) : base() { this._encoding = encoding; } /// <summary> /// Initializes a new instance of the StringWriter class with the /// specified format control and encoding. /// </summary> /// <param name = "encoding">The encoding to report.</param> /// <param name = "formatProvider">An IFormatProvider object that controls formatting.</param> public StringWriterWithEncoding(Encoding encoding, IFormatProvider formatProvider) : base(formatProvider) { this._encoding = encoding; } /// <summary> /// Initializes a new instance of the StringWriter class that writes to the /// specified StringBuilder, and reports the specified encoding. /// </summary> /// <param name = "encoding">The encoding to report.</param> /// <param name = "sb">The StringBuilder to write to. </param> public StringWriterWithEncoding(Encoding encoding, StringBuilder sb) : base(sb) { this._encoding = encoding; } /// <summary> /// Initializes a new instance of the StringWriter class that writes to the specified /// StringBuilder, has the specified format provider, and reports the specified encoding. /// </summary> /// <param name = "encoding">The encoding to report.</param> /// <param name = "sb">The StringBuilder to write to. </param> /// <param name = "formatProvider">An IFormatProvider object that controls formatting.</param> public StringWriterWithEncoding(Encoding encoding, StringBuilder sb, IFormatProvider formatProvider) : base(sb, formatProvider) { this._encoding = encoding; } /// <summary> /// Gets the Encoding in which the output is written. /// </summary> public override Encoding Encoding { get { return this._encoding; } } }} |
Update:
Habe die Klasse mal um Kommentare erweitert.
