Stream类的主要方法

C# Stream.Equals的代码示例

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

Stream.Equals的代码示例1 - ProcessObjects()

    using System.IO;

        /// 
        /// Read all the objects from the source stream and call  for each.
        /// 
        /// The total number of objects read
        public int ProcessObjects()
        {
            this.ValidateHeader();

            // Start reading objects
            int numObjectsRead = 0;
            byte[] curObjectHeader = new byte[NumObjectHeaderBytes];

            while (true)
            {
                bool keepReading = this.ShouldContinueReading(curObjectHeader);
                if (!keepReading)
                {
                    break;
                }

                // Get the length
                long curLength = BitConverter.ToInt64(curObjectHeader, NumObjectIdBytes);

                // Handle the loose object
                using (Stream rawObjectData = new RestrictedStream(this.source, curLength))
                {
                    string objectId = SHA1Util.HexStringFromBytes(curObjectHeader, NumObjectIdBytes);

                    if (objectId.Equals(GVFSConstants.AllZeroSha))
                    {
                        throw new RetryableException("Received all-zero SHA before end of stream");
                    }

                    this.onLooseObject(rawObjectData, objectId);
                    numObjectsRead++;
                }
            }

            return numObjectsRead;
        }
