Int64.TryParse

Syntax

TryParse(Value: String; Var Result: Int64): Boolean;

Parameters

Value. The string value that must be converted to the Int64 type.

Result. Variable, into which the value in case of successful conversion will be placed.

Description

The TryParse method converts a string value to the Int64 type with string correction validation.

Comments

If conversion is successful, the method returns True, and the converted value is placed to the variable specified in the Result parameter.

Example

Sub SampleInt64;
Var
    i: Int64;
    b: Boolean;
Begin
    b := Int64.TryParse("1234567890", i);
    Debug.WriteLine(b.ToString + " : " + i.ToString);
    i := 0;
    b := Int64.TryParse("1234567890.0", i);
    Debug.WriteLine(b.ToString + " : " + i.ToString);
    i := 0;
    b := Int64.TryParse("1 234 567 890", i);
    Debug.WriteLine(b.ToString + " : " + i.ToString);
End Sub SampleInt64;

On executing the example it will be checked if various string values can be converted to the Int64 type. The check and conversion results will be displayed in the development environment console.
