Hello @Ajay String is a class which is alias of system.String if you have a confusion about that then try this write String in application and now right click on it and select GO TO Defination and you will find your answer // Summary: // Represents text as a series of Unicode characters. [Serializable] [ComVisible(true)] public sealed class String : IComparable ICloneable IConvertible IComparable  IEnumerable  IEnumerable IEquatable { // Summary: // Represents the empty string. This field is read-only. public static readonly string Empty; // Summary: // Initializes a new instance of the System.String class to the value indicated // by a specified pointer to an array of Unicode characters. // // Parameters: // value: // A pointer to a null-terminated array of Unicode characters. // // Exceptions: // System.ArgumentOutOfRangeException: // The current process does not have read access to all the addressed characters. // // System.ArgumentNullException: // value is null. // // System.ArgumentException: // value specifies an array that contains an invalid Unicode character or value // specifies an address less than 64000. [CLSCompliant(false)] [SecurityCritical] public String(char* value); // // Summary: // Initializes a new instance of the System.String class to the value indicated // by an array of Unicode characters. // // Parameters: // value: // An array of Unicode characters. [SecuritySafeCritical] public String(char[] value); // // Summary: // Initializes a new instance of the System.String class to the value indicated // by a pointer to an array of 8-bit signed integers. // // Parameters: // value: // A pointer to a null-terminated array of 8-bit signed integers. // // Exceptions: // System.ArgumentNullException: // value is null. // // System.ArgumentException: // A new instance of System.String could not be initialized using value assuming // value is encoded in ANSI. // // System.ArgumentOutOfRangeException: // The length of the new string to initialize which is determined by the null // termination character of value is too large to allocate. // // System.AccessViolationException: // value specifies an invalid address. [CLSCompliant(false)] [SecurityCritical] public String(sbyte* value); // // Summary: // Initializes a new instance of the System.String class to the value indicated // by a specified Unicode character repeated a specified number of times. // // Parameters: // c: // A Unicode character. // // count: // The number of times c occurs. // // Exceptions: // System.ArgumentOutOfRangeException: // count is less than zero. [SecuritySafeCritical] public String(char c int count); // // Summary: // Initializes a new instance of the System.String class to the value indicated // by a specified pointer to an array of Unicode characters a starting character // position within that array and a length. // // Parameters: // value: // A pointer to an array of Unicode characters. // // startIndex: // The starting position within value. // // length: // The number of characters within value to use. // // Exceptions: // System.ArgumentOutOfRangeException: // startIndex or length is less than zero value + startIndex cause a pointer // overflow or the current process does not have read access to all the addressed // characters. Which show that String is a class

Hello Ajay In c# language there are three varieties of data types: Value types Reference types Pointer types So string is a data type that comes under reference type that allows you to assign any string value to a variable. The string type is an alias (another name) for the System.string class. So string is also a class. For more details follow the link below: c# Data types c# String class Thank you.
