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;
"Hello".Log(); //Hello

String

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

int amount = 1000;
string formattedAmount = amount.Separator(); // "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 reverseString = "Thuaanj".ReverseString(); // "jnaauhT"

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

StringEx.IsNumericString("-3.14").Log(); //true
StringEx.IsNumericString("1,000,000.34", ',').Log(); //true

string lorem = StringEx.Lorem; // "lorem ipsum dolor sit"
string lorem = StringEx.LoremShort; // "lorem ipsum dolor sit"
string lorem = StringEx.LoremLong; // "lorem ipsum dolor sit..."
string lorem = StringEx.LoremIpsum(minWords: 4, maxWords: 64, minSentences: 1, maxSentences: 4, numParagraphs: 4); // "lorem ipsum dolor sit..."

//Convert a number to words:
1000.ToWords(); // "one thousand"

//Set Language
Console.OutputEncoding = Encoding.UTF8;

StringEx.SetLanguageToWords(LanguageDefinition.VN);

1000.ToWords(); // "một nghìn"

"abc".Contains(x => x.TextOnly).Log(); //true
"123abc".Contains(x => x.TextOnly).Log(); //false
"abc".Contains(x => x.Number).Log(); //false
"123abc".Contains(x => x.NumberOnly).Log(); //false
"123abc".Contains(x => x.Number).Log(); //true

Number

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

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

"69".ParseInt();
"6.9".ParseFloat();
"3.14".ParseDouble();

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

///Custom function
//One parameter
CalculateEx.AddSimpleFunction("addone", num =>
{
    return ++num;
});
//Many parameter
CalculateEx.AddFunction("sum", agrs =>
{
    return agrs.Sum();
});
//Operator
CalculateEx.AddOperator('?', (a, b) =>
{
    return Random.Shared.Next((int)a, (int)b);
}, 3);

CalculateEx.AddOperator('#', Math.Max, 3);


"addone(1)> ".Log("addone(1)".Calculate()); //2
"1?100> ".Log("1?100".Calculate());
"sum(a,2,3,4,5,6)> ".Log("sum(a,2,3,4,5,6)".Calculate()); //21
"1#2#3#6#5#4> ".Log("1#2#3#6#5#4".Calculate()); //6

DataTable To List

var list = dataTable.ToList<model>();

//Match column name
var list2 = dataTable.ToList<model>(matchCase: true);

//Convert with cache
var list2 = dataTable.ToListCache<model>(matchCase: true);


//Specify the column name other fields
class TestTable{
	[ColumnName("IDX")]
	public string Id { get; set; } = "";
	[ColumnName("FULLNAME")]
	public string Name { get; set; } = "";
}
