  • factorial: "4!".Caculate()
  • percent: "44%".Caculate()

Installation

You can install the library via NuGet Package Manager. Simply search for Library Name and install the latest version.

Usage

Here is an example of how to use the library:

using VTNET.Extensions;

string str = "";
bool isEmpty = str.IsNullOrEmpty(); //true

string str = " ";
bool isEmpty = str.IsNullOrWhiteSpace(); //true

string number = "1000";
bool isNumber = number.IsNumber(); // true

int num = 69;
bool isEven = num.IsEven(); // false

int num2 = 96;
bool isOdd = num2.IsOdd(); // true

string number2 = "1000";
string words = number2.ToWords(); // "one thousand"

int amount = 1000;
string formattedAmount = amount.ToCurrency(); // "1,000.00"

string text = "a   b       c";
string trimmedText = text.RemoveDuplicateSpaces(); // "a b c"

string name = "vo thanh thuan";
string capitalized = name.Capitalize(); // "Vo thanh thuan"

string title = "vo thanh thuan";
string titleCase = title.Title(); // "Vo Thanh Thuan"

string expression = "1+1";
int result = expression.Calculate(); // 2

string titleCase = string.Lorem(); // "lorem ipsum dolor sit vothuan"

"Hello".Log(); //like Console.WriteLine("Hello");

",".Join(listValue); //like string.Join(",", listValue);

//Convert DataTable to List
var list = dataTable.ToList<model>();

Calculate

"sin(30)".Calculate(); //sin(30)> -0.9880316240928618
"sin(30deg)".Calculate(); //sin(30deg)> 0.49999999999999994

"tan(30)".Calculate(); //tan(30)> -6.405331196646276
"tan(30deg)".Calculate(); //tan(30deg)> 0.5773502691896257

"cos(30)".Calculate(); //cos(30)> 0.15425144988758405
"cos(30deg)".Calculate(); //cos(30deg)>0.8660254037844387

"log(30)".Calculate(); //log(30)> 1.4771212547196624

"4!".Calculate(); //4!> 44
"44%".Calculate(); //44%> 0.44

Convert a number to words:

1000.ToWords(); // "one thousand"

//Set Language
LanguageNumberWords.SetLanguageNumberWords(LanguageDefinition.VN);
1000.ToWords(); // "một nghìn"

Check True, False

enum Test{a,b,c,d,e,f,g,h}
var a = new Dictionary<string, string>{ { "a", "1"} };
var b = "1";
var c = new List<string>();
var d = new string[]{"1", "2"};
var e = Test.a;
var f = Test.b;
">> IsTrue:".Log();
"a> ".Log(a.IsTrue()); //true
"b> ".Log(b.IsTrue()); //true
"c> ".Log(c.IsTrue()); //false
"d> ".Log(d.IsTrue()); //true
"e> ".Log(e.IsTrue()); //false
"f> ".Log(f.IsTrue()); //true
"--------------------".Log();
">> IsFalse:".Log();
"a> ".Log(a.IsFalse()); //a> false
"b> ".Log(b.IsFalse()); //b> false
"c> ".Log(c.IsFalse()); //c> true
"d> ".Log(d.IsFalse()); //d> false
"e> ".Log(e.IsFalse()); //e> true
"f> ".Log(f.IsFalse()); //f> false
