C# File.Write的代码示例

通过代码示例来学习C# File.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。


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

File.Write的代码示例1 - IniCheckPermissions()

    using System.IO;

        bool IniCheckPermissions()
        {
            bool deleteAfter = !File.Exists(IniFilename);
            bool hasPermission = false;

            try
            {
                using (FileStream fileStream = File.Open(IniFilename, FileMode.OpenOrCreate, FileAccess.Write))
                {
                    hasPermission = true;
                }
            }
            catch
            {
                hasPermission = false;
            }

            if (File.Exists(IniFilename) && deleteAfter)
                try
                {
                    File.Delete(IniFilename);
