Fields
| FalseString | Represents the Boolean value |
| TrueString | Represents the Boolean value |
Methods
| CompareTo(Boolean) | Compares this instance to a specified Boolean object and returns an integer that indicates their relationship to one another. |
| CompareTo(Object) | Compares this instance to a specified object and returns an integer that indicates their relationship to one another. |
| Equals(Boolean) | Returns a value indicating whether this instance is equal to a specified Boolean object. |
| Equals(Object) | Returns a value indicating whether this instance is equal to a specified object. |
| GetHashCode() | Returns the hash code for this instance. |
| GetTypeCode() | Returns the type code for the Boolean value type. |
| 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. |
| ToString() | Converts the value of this instance to its equivalent string representation (either "True" or "False"). |
| ToString(IFormatProvider) | Converts the value of this instance to its equivalent string representation (either "True" or "False"). |
| TryFormat(Span<Char>, Int32) | Tries to format the value of the current boolean instance into the provided span of characters. |
| TryParse(ReadOnlySpan<Char>, Boolean) | Tries to convert the specified span representation of a logical value to its Boolean equivalent. |
| TryParse(String, Boolean) | Tries to convert the specified string representation of a logical value to its Boolean equivalent. |
Explicit Interface Implementations
| IComparable.CompareTo(Object) | Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object. |
| IConvertible.GetTypeCode() | Returns the TypeCode for this instance. |
| IConvertible.ToBoolean(IFormatProvider) | For a description of this member, see ToBoolean(IFormatProvider). |
| IConvertible.ToByte(IFormatProvider) | For a description of this member, see ToByte(IFormatProvider). |
| IConvertible.ToChar(IFormatProvider) | This conversion is not supported. Attempting to use this method throws an InvalidCastException. |
| IConvertible.ToDateTime(IFormatProvider) | This conversion is not supported. Attempting to use this method throws an InvalidCastException. |
| IConvertible.ToDecimal(IFormatProvider) | For a description of this member, see ToDecimal(IFormatProvider). |

| IConvertible.ToUInt64(IFormatProvider) | For a description of this member, see ToUInt64(IFormatProvider). |
| IParsable<Boolean>.Parse(String, IFormatProvider) | Parses a string into a value. |
| IParsable<Boolean>.TryParse(String, IFormatProvider, Boolean) | |
| ISpanParsable<Boolean>.Parse(ReadOnlySpan<Char>, IFormatProvider) | Parses a span of characters into a value. |
| ISpanParsable<Boolean>.TryParse(ReadOnlySpan<Char>, IFormatProvider, Boolean) | |

Thread Safety
All members of this type are thread safe. Members that appear to modify instance state actually return a new instance initialized with the new value. As with any other type, reading and writing to a shared variable that contains an instance of this type must be protected by a lock to guarantee thread safety.
