C#中的StringWriter与StringReader？
StringReader和StringWriter派生自TextReader和TextWriter
StringWriter用于写入字符串缓冲区。它实现了TextWriter，用于将信息写入字符串。
对于StringWriter-
示例
StringWriter sWriter = new StringWriter();
while(true) {
myChar = strReader.Read();
if(myChar == -1) break;
convertedChar = Convert.ToChar(myChar);
if(convertedChar == '.') {
strWriter.Write(".\n\n");
sReader.Read();
sReader.Read();
}else {
sWriter.Write(convertedChar);
}
}
}StringReader读取字符串-
示例
StringBuilder sbuilder = new StringBuilder();
//附加
sbuilder.AppendLine("Line one characters");
sbuilder.AppendLine("Line two characters");
sbuilder.AppendLine("Line three characters");
//读取字符串
using (StringReader sReader = new StringReader(sbuilder.ToString())) {
string readString = await sReader.ReadToEndAsync();
Console.WriteLine(readString);
}
