C#開源實(shí)用的工具類庫，集成超過1000多種擴(kuò)展方法

作者：大姚 2024-05-30 07:29:59

今天大姚給大家分享一個C#開源（MIT License）、免費(fèi)、實(shí)用且強(qiáng)大的工具類庫，集成超過1000多種擴(kuò)展方法增強(qiáng) .NET Framework 和 .NET Core的使用效率：Z.ExtensionMethods。

前言

直接項(xiàng)目引入類庫使用

在你的對應(yīng)項(xiàng)目中NuGet包管理器中搜索：Z.ExtensionMethods安裝即可使用。

支持.NET Standard 2.0和.NET Framework 4.0 。

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(jié)數(shù)組

將泛型數(shù)組轉(zhuǎn)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;
    }
