通过代码示例来学习C# FileStream.ReadByte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。


FileStream.ReadByte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FileStream.ReadByte() 已经帮大家高亮显示了，大家可以重点学习FileStream.ReadByte() 方法的写法，从而快速掌握该方法的应用。

FileStream.ReadByte的代码示例1 - ReadingFileDoesNotUpdateIndexOrModifiedPaths()

    using System.IO;

        [TestCase, Order(7)]
        public void ReadingFileDoesNotUpdateIndexOrModifiedPaths()
        {
            string gitFileToCheck = "GVFS/GVFS.FunctionalTests/Category/CategoryConstants.cs";
            string virtualFile = this.Enlistment.GetVirtualPathTo(gitFileToCheck);
            ProcessResult initialResult = GitProcess.InvokeProcess(this.Enlistment.RepoRoot, "ls-files --debug -svmodc " + gitFileToCheck);
            initialResult.ShouldNotBeNull();
            initialResult.Output.ShouldNotBeNull();
            initialResult.Output.StartsWith("S ").ShouldEqual(true);
            initialResult.Output.ShouldContain("ctime: 0:0", "mtime: 0:0", "size: 0\t");

            using (FileStream fileStreamToRead = File.OpenRead(virtualFile))
            {
                fileStreamToRead.ReadByte();
            }

            this.Enlistment.WaitForBackgroundOperations();

            ProcessResult afterUpdateResult = GitProcess.InvokeProcess(this.Enlistment.RepoRoot, "ls-files --debug -svmodc " + gitFileToCheck);
            afterUpdateResult.ShouldNotBeNull();
            afterUpdateResult.Output.ShouldNotBeNull();
            afterUpdateResult.Output.StartsWith("S ").ShouldEqual(true);
            afterUpdateResult.Output.ShouldContain("ctime: 0:0", "mtime: 0:0", "size: 0\t");

            GVFSHelpers.ModifiedPathsShouldNotContain(this.Enlistment, this.fileSystem, gitFileToCheck);
        }
