示例1: ReadLineAsync
// Unlike normal ReadLine, this returns the line content with new line characters.
public static async Task<StreamResult> ReadLineAsync(TextReader reader, StringBuilder builder)
{
bool written = false;
char[] chars = new char[1];
while (true)
{
int num = await reader.ReadAsync(chars, 0, chars.Length);
if (num <= 0)
{
return written ? new StreamResult(builder.ToString(), hasMore:reader.Peek() != -1) : null;
}
if (chars[0] == '\r' || chars[0] == '\n')
{
builder.Append(chars[0]);
if (chars[0] == '\r' && reader.Peek() == (int)'\n')
{
builder.Append((char)reader.Read());
}
return new StreamResult(builder.ToString(), hasMore: reader.Peek() != -1);
}
written = true;
builder.Append(chars[0]);
// to anticipate last non-ending line
if (reader.Peek() == -1)
{
return written ? new StreamResult(builder.ToString(), hasMore: reader.Peek() != -1) : null;
}
}
}
示例2: SkipUntilAsync
public static async Task SkipUntilAsync(TextReader reader, string token)
{
if (reader == null) throw new ArgumentNullException("reader");
if (token == null) return;
var charSet = token.ToCharArray();
var buffer = new char[charSet.Length];
var actual = await reader.ReadAsync(buffer, 0, charSet.Length);
if (actual != charSet.Length)
{
return;
}
do
{
if (buffer.SequenceEqual(charSet))
{
return;
}
Array.Copy(buffer, 1, buffer, 0, charSet.Length - 1);
actual = await reader.ReadAsync(buffer, charSet.Length - 1, 1);
} while (actual == 1);
}
