StringWriter vs StringReader in C#?
StringReader and StringWriter derive from TextReader and TextWriter
StringWriter is used for writing into a string buffer. It implements a TextWriter for writing information to a string.
For StringWriter −
Example
StringWriter sWriter = new StringWriter();
while(true) {
myChar = strReader.Read();
if(myChar == -1) break;
convertedChar = Convert.ToChar(myChar);
if(convertedChar == '.') {
strWriter.Write(".
");
sReader.Read();
sReader.Read();
}else {
sWriter.Write(convertedChar);
}
}
}StringReader to read a string −
Example
StringBuilder sbuilder = new StringBuilder();
// append
sbuilder.AppendLine("Line one characters");
sbuilder.AppendLine("Line two characters");
sbuilder.AppendLine("Line three characters");
// read string
using (StringReader sReader = new StringReader(sbuilder.ToString())) {
string readString = await sReader.ReadToEndAsync();
Console.WriteLine(readString);
}
