C# में StringBuilder.ToString() विधि का उपयोग aStringBuilder के मान को एक स्ट्रिंग में बदलने के लिए किया जाता है।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public override string ToString (); public string ToString (int begnIndex, int len);
ऊपर, पैरामीटर begnIndex इस उदाहरण में सबस्ट्रिंग की शुरुआती स्थिति है, जबकि लेन सबस्ट्रिंग की लंबाई है।
उदाहरण
आइए अब एक उदाहरण देखें -
using System;
using System.Text;
public class Demo{
public static void Main(){
StringBuilder strBuilder = new StringBuilder("Katie");
Console.WriteLine("String = "+strBuilder.ToString());
Console.WriteLine("\nStringBuilder capacity = "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
strBuilder.EnsureCapacity(35);
Console.WriteLine("\nStringBuilder capacity= "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
strBuilder.EnsureCapacity(0);
strBuilder.Length = 0;
Console.WriteLine("\nStringBuilder capacity= "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
}
} आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
String = Katie StringBuilder capacity = 16 StringBuilder length = 5 StringBuilder capacity= 35 StringBuilder length = 5 StringBuilder capacity= 35 StringBuilder length = 0
उदाहरण
आइए अब एक और उदाहरण देखें -
using System;
using System.Text;
public class Demo{
public static void Main(){
StringBuilder strBuilder = new StringBuilder("TomHanks");
Console.WriteLine("StringBuilder = "+strBuilder.ToString());
Console.WriteLine("String = "+strBuilder.ToString(3, 5));
Console.WriteLine("\nStringBuilder capacity = "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
strBuilder.EnsureCapacity(35);
Console.WriteLine("\nStringBuilder capacity= "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
strBuilder.EnsureCapacity(0);
strBuilder.Length = 0;
Console.WriteLine("\nStringBuilder capacity= "+strBuilder.Capacity);
Console.WriteLine("StringBuilder length = "+strBuilder.Length);
}
} आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
StringBuilder = TomHanks String = Hanks StringBuilder capacity = 16 StringBuilder length = 8 StringBuilder capacity= 35 StringBuilder length = 8 StringBuilder capacity= 35 StringBuilder length = 0
