C# Stream.Read的代码示例

通过代码示例来学习C# Stream.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。


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

Stream.Read的代码示例1 - LoadDocumentWithStream()

    using System.IO;

    public static void LoadDocumentWithStream()
    {
      using( var fs = new FileStream( DocumentSample.DocumentSampleResourcesDirectory + @"First.docx", FileMode.Open, FileAccess.Read, FileShare.Read ) )
      {
        using( var doc = DocX.Load( fs ) )
        {
          // Add a title
          doc.InsertParagraph( 0, "Load Document with Stream", false ).FontSize( 15d ).SpacingAfter( 50d ).Alignment = Alignment.center;

          // Insert a Paragraph into this document.
          var p = doc.InsertParagraph();

          // Append some text and add formatting.
          p.Append( "A small paragraph was added." );

          doc.SaveAs( DocumentSample.DocumentSampleOutputDirectory + @"LoadDocumentWithStream.docx" );
        }
      }
    }
