C＃のSingle.ToStringメソッド

C＃のSingle.ToString（）メソッドは、このインスタンスの数値を同等の文字列表現に変換するために使用されます。

構文

構文は次のとおりです-

public override string ToString ();

例

例を見てみましょう-

using System;
public class Demo {
   public static void Main(){
      float f1 = 10.0f/0.0f;
      float f2 = -3.0f;
      Console.WriteLine("Value1 (String representation) = "+f1.ToString());
      Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
      Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
      Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
      Console.WriteLine("Is Value1 NaN? = "+Single.IsNaN(f1));
      Console.WriteLine("Is Value1 a positive infinity? = "+Single.IsPositiveInfinity(f1));
      Console.WriteLine("\nValue1 (String representation) = "+f2.ToString());
      Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
      Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
      Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
      Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
      Console.WriteLine("Is Value2 a positive infinity? = "+Single.IsPositiveInfinity(f2));
   }
}

出力

これにより、次の出力が生成されます-

Value1 (String representation) = ∞
Hashcode for Value1 = 2139095040
TypeCode for Value1 = Single
Is Value1 value is positive or negative infinity? = True
Is Value1 NaN? = False
Is Value1 a positive infinity? = True
Value1 (String representation) = -3
Hashcode for Value2 = -1069547520
TypeCode for Value2 = Single
Is Value2 value is positive or negative infinity? = False
Is Value2 NaN? = False
Is Value2 a positive infinity? = False

例

別の例を見てみましょう-

using System;
public class Demo {
   public static void Main(){
      float f1 = 5.0f/0.0f;
      float f2 = 0.0f/0.0f;
      Console.WriteLine("Value1 (String representation) = "+f1.ToString());
      Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
      Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
      Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
      Console.WriteLine("Is Value1 NaN? = "+Single.IsNaN(f1));
      Console.WriteLine("Is Value1 a negative infinity? = "+Single.IsNegativeInfinity(f1));
      Console.WriteLine("\nValue2 (String representation) = "+f2.ToString());
      Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
      Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
      Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
      Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
      Console.WriteLine("Is Value2 a negative infinity? = "+Single.IsNegativeInfinity(f2));
   }
}
