部分擴展方法展示

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();        }    }}

解壓GZip字節數組

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 bytes                using (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 bytes                using (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);                }            }        }    }}

將泛型數組轉換為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;    }}
