Jasmine.Extensions

Jasmine.Extensions 是一组用于 .NET 的轻量级扩展方法集合,包含对数值(decimal/double/float)、字符串、集合(List)与 DataTable 互转等常用功能的扩展,便于在项目中复用常见工具方法。

特性

  • 精确的四舍五入(向远离零方向的舍入)扩展:decimal, double, float 的 ToFixed 方法
  • 常用字符串安全转换:ToInt、ToLong、ToDecimal、ToDouble、ToFloat、ToBool、ToGuid、ToDateTime 等
  • 字符串判空简写:IsNullOrEmpty、IsNullOrWhiteSpace(对输入会先做 Trim)
  • List 辅助:AddRangeIfNotExists(仅添加不存在的元素)、ToDataTable(将对象列表转换为 DataTable)
  • DataTable 辅助:ToList<T>(把 DataTable 的行映射回对象列表)

安装

当前包在项目内以 Jasmine.Extensions 打包,示例版本见 bin/Debug(例如 Jasmine.Extensions.1.0.0.nupkg)。使用 NuGet 安装:

dotnet add package Jasmine.Extensions --version 1.0.0

(如果你本地已产生 nupkg,也可以使用 dotnet nuget add source / 本地源或直接引用项目来调试)

名称空间

各扩展按功能划分到不同名称空间:

  • Jasmine.Extensions.Decimals — decimal 扩展
  • Jasmine.Extensions.Doubles — double 扩展
  • Jasmine.Extensions.Floats — float 扩展
  • Jasmine.Extensions.Strings — 字符串扩展
  • Jasmine.Extensions.Lists — List / DataTable 扩展
  • Jasmine.Extensions.Tables — DataTable → List<T>

示例:在文件顶部添加 using Jasmine.Extensions.Strings; 即可使用字符串扩展方法。

快速示例

下面均为 C# 示例,演示常见用法。

数值舍入(ToFixed)

using Jasmine.Extensions.Decimals;
using Jasmine.Extensions.Doubles;
using Jasmine.Extensions.Floats;

decimal d = 1.2345m;
var dFixed = d.ToFixed(2); // 1.23 (向远离零舍入)

double x = 2.3456;
var xFixed = x.ToFixed(3);

float f = 3.14159f;
var fFixed = f.ToFixed(2);

List 操作

using Jasmine.Extensions.Lists;

var list = new List<int> { 1, 2 };
list.AddRangeIfNotExists(new[] { 2, 3, 4 }); // 只添加 3 和 4

// 将对象列表转换为 DataTable
var people = new List<Person> { new Person { Id = 1, Name = "Alice" } };
var table = people.ToDataTable();

DataTable → List<T>

using Jasmine.Extensions.Tables;
using System.Data;

DataTable table = /* 从其它来源获得 */ new DataTable();
// 假设 DataTable 的列与类型与 Person 的属性匹配
var list = table.ToList<Person>();

字符串转换与判空

using Jasmine.Extensions.Strings;

string s = "2023-10-27T12:34:56Z";
var dt = s.ToDateTime(); // 解析若失败返回 DateTime.UtcNow

string guidStr = "d2719f2b-...";
var guid = guidStr.ToGuid(); // 解析失败返回 Guid.Empty

string num = "123";
int i = num.ToInt(); // 123
bool b = "true".ToBool(); // true

string empty = "  ";
var isEmpty = empty.IsNullOrWhiteSpace(); // true
