Definition

Overloads

Parse(ReadOnlySpan<Char>)

Converts the specified span representation of a logical value to its Boolean equivalent.

Parse(String)

Converts the specified string representation of a logical value to its Boolean equivalent.

Parse(ReadOnlySpan<Char>)

Source:
Boolean.cs
Source:
Boolean.cs
Source:
Boolean.cs

Converts the specified span representation of a logical value to its Boolean equivalent.

public:
 static bool Parse(ReadOnlySpan<char> value);
public static bool Parse (ReadOnlySpan<char> value);
static member Parse : ReadOnlySpan<char> -> bool
Public Shared Function Parse (value As ReadOnlySpan(Of Char)) As Boolean

Parameters

value
ReadOnlySpan<Char>

A span containing the characters representing the value to convert.

Returns

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

Applies to

Parse(String)

Source:
Boolean.cs
Source:
Boolean.cs
Source:
Boolean.cs

Converts the specified string representation of a logical value to its Boolean equivalent.

public:
 static bool Parse(System::String ^ value);
public static bool Parse (string value);
static member Parse : string -> bool
Public Shared Function Parse (value As String) As Boolean

Parameters

value
String

A string containing the value to convert.

Returns

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

Exceptions

value is null.

value is not equivalent to TrueString or FalseString.

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.
