StreamReader.Read的代码示例1 - GetPersistedValue()
using System.IO;
private static string GetPersistedValue(string dotGVFSRoot, string key)
{
string metadataPath = Path.Combine(dotGVFSRoot, RepoMetadataName);
string json;
using (FileStream fs = new FileStream(metadataPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite | FileShare.Delete))
using (StreamReader reader = new StreamReader(fs))
{
while (!reader.EndOfStream)
{
json = reader.ReadLine();
json.Substring(0, 2).ShouldEqual("A ");
KeyValuePair kvp = JsonConvert.DeserializeObject>(json.Substring(2));
if (kvp.Key == key)
{
return kvp.Value;
}
}
}
return null;
