如何以共享方式打开.txt文件

[wubaowang]

            using (StreamReader srd = new StreamReader(fileName, System.Text.Encoding.Default))
            {
                while ((objet = srd.ReadLine()) != null)
                {
                    txtRead += objet + "\r\n";
                    rows++;
                }
                srd.Close();
            }

如何以共享方式打开.txt文件

谁告诉你StreamReader打开文件不是共享方式的？

[genlinux]

FileStream fs = File.Open(file, FileMode.Open,FileAccess.Read,FileShare.Read);
默认下打开的文件是被打开者拥有的， 而且是不分享的。
using (StreamReader srd = new StreamReader(fs))
{
while ((objet = srd.ReadLine()) != null)
{
txtRead += objet + "\r\n";
rows++;
}
srd.Close();
}

接分喽

[lake_cx]

public StreamReader(string path, Encoding encoding, bool detectEncodingFromByteOrderMarks, int bufferSize)
{
    if ((path == null) || (encoding == null))
    {
        throw new ArgumentNullException((path == null) ? "path" : "encoding");
    }
    if (path.Length == 0)
    {
        throw new ArgumentException(Environment.GetResourceString("Argument_EmptyPath"));
    }
    if (bufferSize <= 0)
    {
        throw new ArgumentOutOfRangeException("bufferSize", Environment.GetResourceString("ArgumentOutOfRange_NeedPosNum"));
    }
    Stream stream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read, 0x1000, FileOptions.SequentialScan);
    this.Init(stream, encoding, detectEncodingFromByteOrderMarks, bufferSize);
}

Read好像就是共享的.
