# String.Length Właściwość

## Definicja

Pobiera liczbę znaków w bieżącym String obiekcie.Gets the number of characters in the current String object.

``````public:
property int Length { int get(); };``````
``public int Length { get; }``
``member this.Length : int``
``Public ReadOnly Property Length As Integer``

#### Wartość właściwości

Int32

Liczba znaków w bieżącym ciągu.The number of characters in the current string.

Poniższy przykład demonstruje Length Właściwość.The following example demonstrates the Length property.

``````// Sample for String::Length
using namespace System;
int main()
{
String^ str = "abcdefg";
Console::WriteLine( "1) The length of '{0}' is {1}", str, str->Length );
Console::WriteLine( "2) The length of '{0}' is {1}", "xyz", ((String^)"xyz")->Length );
int length = str->Length;
Console::WriteLine( "1) The length of '{0}' is {1}", str, length );
}

/*
This example displays the following output:
1) The length of 'abcdefg' is 7
2) The length of 'xyz' is 3
3) The length of 'abcdefg' is 7
*/
``````
``````string str = "abcdefg";
Console.WriteLine("1) The length of '{0}' is {1}", str, str.Length);
Console.WriteLine("2) The length of '{0}' is {1}", "xyz", "xyz".Length);

int length = str.Length;
Console.WriteLine("3) The length of '{0}' is {1}", str, length);

// This example displays the following output:
//    1) The length of 'abcdefg' is 7
//    2) The length of 'xyz' is 3
//    3) The length of 'abcdefg' is 7
``````
``````Class Sample
Public Shared Sub Main()
Dim str As String = "abcdefg"
Console.WriteLine("1) The length of '{0}' is {1}", str, str.Length)
Console.WriteLine("2) The length of '{0}' is {1}", "xyz", "xyz".Length)
Dim length As Integer = str.Length
Console.WriteLine("1) The length of '{0}' is {1}", str, length)
End Sub
End Class

'This example displays the following output:
'    1) The length of 'abcdefg' is 7
'    2) The length of 'xyz' is 3
'    3) The length of 'abcdefg' is 7

## Uwagi

LengthWłaściwość zwraca liczbę Char obiektów w tym wystąpieniu, a nie liczbę znaków Unicode.The Length property returns the number of Char objects in this instance, not the number of Unicode characters. Przyczyną jest to, że znak Unicode może być reprezentowany przez więcej niż jeden Char .The reason is that a Unicode character might be represented by more than one Char. Użyj System.Globalization.StringInfo klasy do pracy z każdym znakiem Unicode zamiast każdego Char .Use the System.Globalization.StringInfo class to work with each Unicode character instead of each Char.

W niektórych językach, takich jak C i C++, znak null wskazuje koniec ciągu.In some languages, such as C and C++, a null character indicates the end of a string. W programie .NET znak null może być osadzony w ciągu.In .NET, a null character can be embedded in a string. Gdy ciąg zawiera jeden lub więcej znaków null, są one uwzględnione w długości łącznego ciągu.When a string includes one or more null characters, they are included in the length of the total string. Na przykład, w poniższym ciągu, podciągi "ABC" i "def" są oddzielane znakiem null.For example, in the following string, the substrings "abc" and "def" are separated by a null character. LengthWłaściwość zwraca wartość 7, co oznacza, że zawiera sześć znaków alfabetu, a także znak null.The Length property returns 7, which indicates that it includes the six alphabetic characters as well as the null character.

``````using namespace System;
using namespace System::Text;

void main()
{
String^ characters = "abc" + L'0' + "def";
Console::WriteLine(characters->Length);        // Displays 7
}
``````
``````string characters = "abc\u0000def";
Console.WriteLine(characters.Length); // Displays 7
``````
``````Imports System.Text

Module Example

Public Sub Main()
Dim characters As String = "abc" + ChrW(0) + "def"
Console.WriteLine(characters.Length)       ' Displays 7
End Sub
End Module
