前言
今天大姚给大家分享一个C#开源（MIT License）、免费、实用且强大的工具类库，集成超过1000多种扩展方法增强 .NET Framework 和 .NET Core的使用效率：Z.ExtensionMethods。
直接项目引入类库使用
在你的对应项目中NuGet包管理器中搜索：Z.ExtensionMethods安装即可使用。
支持.NET Standard 2.0和.NET Framework 4.0 。
项目源代码
部分扩展方法展示
MD5哈希算法
public static partial class Extensions
{/// <summary>/// A Stream extension method that converts the @this to a md 5 hash./// </summary>/// <param name="this">The @this to act on.</param>/// <returns>@this as a string.</returns>public static string ToMD5Hash(this Stream @this){using (MD5 md5 = MD5.Create()){byte[] hashBytes = md5.ComputeHash(@this);var sb = new StringBuilder();foreach (byte bytes in hashBytes){sb.Append(bytes.ToString("X2"));}return sb.ToString();}}
}
解压GZip字节数组
public static partial class Extensions
{/// <summary>/// A byte[] extension method that decompress the byte array gzip to string./// </summary>/// <param name="this">The @this to act on.</param>/// <returns>The byte array gzip to string.</returns>public static string DecompressGZip(this byte[] @this){const int bufferSize = 1024;using (var memoryStream = new MemoryStream(@this)){using (var zipStream = new GZipStream(memoryStream, CompressionMode.Decompress)){// Memory stream for storing the decompressed bytesusing (var outStream = new MemoryStream()){var buffer = new byte[bufferSize];int totalBytes = 0;int readBytes;while ((readBytes = zipStream.Read(buffer, 0, bufferSize)) > 0){outStream.Write(buffer, 0, readBytes);totalBytes += readBytes;}return Encoding.Default.GetString(outStream.GetBuffer(), 0, totalBytes);}}}}/// <summary>/// A byte[] extension method that decompress the byte array gzip to string./// </summary>/// <param name="this">The @this to act on.</param>/// <param name="encoding">The encoding.</param>/// <returns>The byte array gzip to string.</returns>public static string DecompressGZip(this byte[] @this, Encoding encoding){const int bufferSize = 1024;using (var memoryStream = new MemoryStream(@this)){using (var zipStream = new GZipStream(memoryStream, CompressionMode.Decompress)){// Memory stream for storing the decompressed bytesusing (var outStream = new MemoryStream()){var buffer = new byte[bufferSize];int totalBytes = 0;int readBytes;while ((readBytes = zipStream.Read(buffer, 0, bufferSize)) > 0){outStream.Write(buffer, 0, readBytes);totalBytes += readBytes;}return encoding.GetString(outStream.GetBuffer(), 0, totalBytes);}}}}
}
将泛型数组转换为DataTable
public static partial class Extensions
{/// <summary>/// A T[] extension method that converts the @this to a data table./// </summary>/// <typeparam name="T">Generic type parameter.</typeparam>/// <param name="this">The @this to act on.</param>/// <returns>@this as a DataTable.</returns>public static DataTable ToDataTable<T>(this T[] @this){Type type = typeof (T);PropertyInfo[] properties = type.GetProperties(BindingFlags.Public | BindingFlags.Instance);FieldInfo[] fields = type.GetFields(BindingFlags.Public | BindingFlags.Instance);var dt = new DataTable();foreach (PropertyInfo property in properties){dt.Columns.Add(property.Name, property.PropertyType);}foreach (FieldInfo field in fields){dt.Columns.Add(field.Name, field.FieldType);}foreach (T item in @this){DataRow dr = dt.NewRow();foreach (PropertyInfo property in properties){dr[property.Name] = property.GetValue(item, null);}foreach (FieldInfo field in fields){dr[field.Name] = field.GetValue(item);}dt.Rows.Add(dr);}return dt;}
