C# Stream.Write的代码示例

通过代码示例来学习C# Stream.Write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。

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

Stream.Write的代码示例1 - AppendToNewlineSeparatedFile()

    using System.IO;

        public static void AppendToNewlineSeparatedFile(PhysicalFileSystem fileSystem, string filename, string newContent)
        {
            using (Stream fileStream = fileSystem.OpenFileStream(filename, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite, false))
            {
                using (StreamReader reader = new StreamReader(fileStream))
                using (StreamWriter writer = new StreamWriter(fileStream))
                {
                    long position = reader.BaseStream.Seek(0, SeekOrigin.End);
                    if (position > 0)
                    {
                        reader.BaseStream.Seek(position - 1, SeekOrigin.Begin);
                    }

                    string lastCharacter = reader.ReadToEnd();
                    if (lastCharacter != "\n" && lastCharacter != string.Empty)
                    {
                        writer.Write("\n");
                    }
