Convert Class in C#
The Convert Class has methods to convert a base data type to another base data type. Let us see some examples −
The Convert.ToBoolean() method in C# is used to convert a specified value to an equivalent Boolean value.
Syntax
Following is the syntax −
public static bool ToBoolean (string val, IFormatProvider provider);
Above, Val is a string that contains the value of either TrueString or FalseString, whereas the provider is an object that supplies culture-specific formatting information.
Example
Let us now see an example to implement the Convert.ToBoolean() method −
using System; using System.Globalization; public class Demo { public static void Main(){ CultureInfo cultures = new CultureInfo("en-US"); String str = "true"; Console.WriteLine("Converted bool value..."); bool res = Convert.ToBoolean(str, cultures); Console.Write("{0}", res); } }
Output
This will produce the following output −
Converted bool value... True
The Convert.ToDouble() method in C# converts the specified string representation of a number to an equivalent double-precision floating-point number, using the specified culture-specific formatting information.
Syntax
Following is the syntax −
public static double ToDouble (string val, IFormatProvider provider);
Above, the value is a string that contains the number to convert, whereas the provider is an object that supplies culture-specific formatting information.
Example
Let us now see an example to implement the Convert.ToDouble() method −
using System; using System.Globalization; public class Demo { public static void Main(){ String val = "876876, 878"; NumberFormatInfo formatProvider = new NumberFormatInfo(); formatProvider.NumberDecimalSeparator = ", "; formatProvider.NumberGroupSeparator = "."; formatProvider.NumberGroupSizes = new int[] { 2 }; Console.WriteLine("Converted Decimal value..."); double res = Convert.ToDouble(val, formatProvider); Console.Write("{0}", res); } }
Output
This will produce the following output −
Converted Decimal value... 876876.878
The Convert.ToDecimal() method in C# converts the specified string representation of a number to an equivalent decimal number, using the specified culture-specific formatting information.
Output
Following is the syntax −
public static decimal ToDecimal (string val, IFormatProvider provider);
Above, Val is a string that contains a number to convert, whereas the provider is an object that supplies culture-specific formatting information.
Example
Let us now see an example to implement the Convert.ToDecimal() method −
using System; using System.Globalization; public class Demo { public static void Main(){ CultureInfo cultures = new CultureInfo("en-US"); String val = "8787"; Console.WriteLine("Converted Decimal value..."); decimal res = Convert.ToDecimal(val, cultures); Console.Write("{0}", res); } }
Output
This will produce the following output −
Converted Decimal value... 8787
