通过代码示例来学习C# StreamReader.Read方法

通过代码示例来学习编程是非常高效的。
1. 代码示例提供了一个具体而直观的学习环境，使初学者能够立即看到编程概念和语法的实际应用。
2. 通过分析和模仿现有的代码实例，初学者可以更好地理解编程逻辑和算法的工作原理。
3. 代码实例往往涵盖了多种编程技巧和最佳实践，通过学习和模仿这些实例，学习者可以逐步掌握如何编写高效、可读性强和可维护的代码。这对于初学者来说，是一种快速提升编程水平的有效途径。


StreamReader.Read是C#的System.IO命名空间下中的一个方法, 小编为大家找了一些网络大拿们常见的代码示例，源码中的StreamReader.Read() 已经帮大家高亮显示了，大家可以重点学习StreamReader.Read() 方法的写法，从而快速掌握该方法的应用。

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;
        }
