public:
 static bool Parse(System::String ^ value);

public static bool Parse(string value);

static member Parse : string -> bool

Parameters

value

String

A string containing the value to convert.

true if value is equivalent to TrueString; false if value is equivalent to FalseString.

Exceptions

Examples

The following code example illustrates the use of Parse method.

Boolean val;
String^ input;
input = Boolean::TrueString;
val = Boolean::Parse( input );
Console::WriteLine(  "'{0}' parsed as {1}", input, val );
// The example displays the following output:
//       'True' parsed as True

bool val;
string input;

input = bool.TrueString;
val = bool.Parse(input);
Console.WriteLine("'{0}' parsed as {1}", input, val);
// The example displays the following output:
//       'True' parsed as True

let input = bool.TrueString
let value = bool.Parse input
printfn $"'{input}' parsed as {value}"
// The example displays the following output:
//       'True' parsed as True

Dim val As Boolean
Dim input As String

input = Boolean.TrueString
val = Boolean.Parse(input)
Console.WriteLine("'{0}' parsed as {1}", input, val)
' The example displays the following output:
'       'True' parsed as True

Remarks

The value parameter, optionally preceded or trailed by white space, must contain either TrueString or FalseString; otherwise, an exception is thrown. The comparison is case-insensitive.
