var result = " ".DefaultIfEmpty("defaultValue"); // defaultValue
var result = "someValue".DefaultIfEmpty("defaultValue"); // someValue
Casts string to specified type or throws if cast is impossible and
throwIfInvalidCast set to true.var result = "123,45".Cast(typeof(float?), true); // 123.45F
var result = "123,45abc".Cast(typeof(float?), true); // throws InvalidCastException
var result = "123,45abc".Cast(typeof(float?), false); // null
private enum FooBarBaz
{
Foo,
Bar,
Baz
}
var result = "Bar".Cast(typeof(FooBarBaz?), false); // FooBarBaz.Bar
Formats string value into hyphen case format. For example "ToHyphenCase" will be formated into "to-hyphen-case".
var result = "ToHyphenCase".ToHyphenCase() // to-hyphen-case
Formats string value into camel case format. For example "ToCamelCase" will be formated into "toCamelCase".
var result = "ToCamelCase".ToCamelCase() // toCamelCase
Formats string value into snake case format. For example "ToSnakeCase" will be formated into "to_snake_case".
var result = "ToSnakeCase".ToSnakeCase() // to_snake_case
Returns a value indicating whether a specified string occurs within this string, using the specified comparison rules. Method could be useful to projects prior to .net standard 2.1. Similar method added to
string in .net standard 2.1.var result = "QwErTy".Contains("wert", StringComparison.Ordinal) // false
var result = "QwErTy".Contains("wert", StringComparison.OrdinalIgnoreCase) // true
Returns a new string in which all occurrences of a specified string in the current instance are replaced with another specified string using provided comparison rule. Method could be useful to projects prior to .net standard 2.1. Similar method added to
string in .net standard 2.1.var result = "QwErTyQwErTy".Replace("WeR", "123", StringComparison.Ordinal) // QwErTyQwErTy
var result = "QwErTyQwErTy".Replace("WeR", "123", StringComparison.OrdinalIgnoreCase) // Q123TyQ123Ty
