 ## Remarks

  A string is a sequential collection of characters that's used to represent text. A <xref:System.String> object is a sequential collection of <xref:System.Char?displayProperty=nameWithType> objects that represent a string; a <xref:System.Char?displayProperty=nameWithType> object corresponds to a UTF-16 code unit. The value of the <xref:System.String> object is the content of the sequential collection of <xref:System.Char?displayProperty=nameWithType> objects, and that value is immutable (that is, it is read-only). For more information about the immutability of strings, see the [Immutability and the StringBuilder class](#Immutability) section. The maximum size of a <xref:System.String> object in memory is 2-GB, or about 1 billion characters.
 
 For more information about Unicode, UTF-16, code units, code points, and the <xref:System.Char> and <xref:System.Text.Rune> types, see [Introduction to character encoding in .NET](/dotnet/standard/base-types/character-encoding-introduction).
