C# UInt32 TryParse(String, UInt32)

Description

UInt32 TryParse(String, UInt32) tries to convert the string representation of a number to its 32-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded or failed.

Syntax

UInt32.TryParse(String, UInt32) has the following syntax.

[CLSCompliantAttribute(false)]//from   w  w w .ja v  a2s .  c o m
public static bool TryParse(
  string s,
  out uint result
)

Parameters

UInt32.TryParse(String, UInt32) has the following parameters.

• s - A string that represents the number to convert.
• result - When this method returns, contains the 32-bit unsigned integer value that is equivalent to the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null or String.Empty, is not of the correct format, or represents a number that is less than UInt32.MinValue or greater than UInt32.MaxValue. This parameter is passed uninitialized.

Returns

UInt32.TryParse(String, UInt32) method returns true if s was converted successfully; otherwise, false.

Example

The following example calls the TryParse(String, UInt32) method once for each element in a string array.

//from  ww w.j ava  2 s .com
using System;
public class MainClass{
  public static void Main(String[] argv){  
    string[] numericStrings = { "1234.8", "+1234.7", "12345.",  
                                "   12345667  ", "(0)", "-0", "-1", 
                                "+1234567", "18-", "123456", "12,345", 
                                "  1234567 ", "12345000" };
    uint number;
    foreach (string numericString in numericStrings)
    {
       if (UInt32.TryParse(numericString, out number)) 
          Console.WriteLine("Converted '{0}' to {1}.", numericString, number);
       else
          Console.WriteLine("Cannot convert '{0}' to a UInt32.", numericString);
    }
  }
}
    

The code above generates the following result.
