C# File.Copy的代码示例

通过代码示例来学习C# File.Copy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.Copy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.Copy() 已经帮大家高亮显示了，大家可以重点学习File.Copy() 方法的写法，从而快速掌握该方法的应用。

File.Copy的代码示例1 - Execute()

    using System.IO;

        public override bool Execute()
        {
            string templateFilePath = this.Template.ItemSpec;
            IDictionary properties = ParseProperties(this.Template.GetMetadata("Properties"));

            string outputFileDirectory = Path.GetDirectoryName(this.OutputFile);

            if (!File.Exists(templateFilePath))
            {
                this.Log.LogError("Failed to find template file '{0}'.", templateFilePath);
                return false;
            }

            // Copy the template to the destination to keep the same file mode bits/ACLs as the template
            File.Copy(templateFilePath, this.OutputFile, true);

            this.Log.LogMessage(MessageImportance.Low, "Reading template contents");
            string template = File.ReadAllText(this.OutputFile);

            this.Log.LogMessage(MessageImportance.Normal, "Compiling template '{0}'", templateFilePath);
            string compiled = Compile(template, properties);

            if (!Directory.Exists(outputFileDirectory))
            {
                this.Log.LogMessage(MessageImportance.Low, "Creating output directory '{0}'", outputFileDirectory);
                Directory.CreateDirectory(outputFileDirectory);
            }

            this.Log.LogMessage(MessageImportance.Normal, "Writing compiled template to '{0}'", this.OutputFile);
            File.WriteAllText(this.OutputFile, compiled);

            this.CompiledTemplate = new TaskItem(this.OutputFile, this.Template.CloneCustomMetadata());

            return true;
        }
