C# StreamReader.Peek的代码示例

通过代码示例来学习C# StreamReader.Peek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。


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

StreamReader.Peek的代码示例1 - CreateInnerSourceDocument()

    using System.IO;

        private static RazorSourceDocument CreateInnerSourceDocument(Stream stream, Encoding encoding, RazorSourceDocumentProperties properties)
        {
            var streamLength = (int)stream.Length;

                using (reader)
                {
                    reader.Peek();      // Just to populate the encoding

                    if (encoding == null)
                    {
                        contentEncoding = reader.CurrentEncoding;

                                reader.CurrentEncoding.EncodingName));
                    }

                    if (streamLength > LargeObjectHeapLimitInChars)
                    {
                        // If the resulting string would end up on the large object heap, then use LargeTextSourceDocument.
                        return new LargeTextSourceDocument(
                            reader,
                            LargeObjectHeapLimitInChars,
                            contentEncoding,
                            properties);
                    }

                    content = reader.ReadToEnd();
                }
            }

            return new StringSourceDocument(content, contentEncoding, properties);
        }
