C# | Convert.ToUInt32(String, IFormatProvider) Method
Last Updated :
11 Jul, 2025
This method is used to converts the specified string representation of a number to an equivalent 32-bit unsigned integer, using the specified culture-specific formatting information.
Syntax:
public static uint ToUInt32 (string value, IFormatProvider provider);
Parameters:
- value : It is a string that contains the number to convert.
- provider : It is an object that supplies culture-specific formatting information.
Return Value: This method returns a 32-bit unsigned integer that is equivalent to the number in
value, or 0 (zero) if
value is
null.
Exceptions:
- FormatException: If the value does not consist of an optional sign followed by a sequence of digits (0 through 9).
- OverFlowException: If the value represents a number that is less than MinValue or greater than MaxValue.
Below programs illustrate the use of
Convert.ToUInt32(String, IFormatProvider) Method:
Example 1:
csharp
// C# program to demonstrate the
// Convert.ToUInt32() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of CultureInfo
CultureInfo cultures = new CultureInfo("en-US");
// declaring and initializing String array
string[] values = {"12345", "+12345",
"123456789"};
// calling get() Method
Console.Write("Converted uint value"
+ " from a specified string ");
for (int j = 0; j < values.Length; j++)
{
get(values[j], cultures);
}
}
catch (FormatException e)
{
Console.WriteLine("\n");
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
catch (OverflowException e)
{
Console.WriteLine("\n");
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
// Defining get() method
public static void get(string s,
CultureInfo cultures)
{
// converting string to specified uint
uint val = Convert.ToUInt32(s, cultures);
// display the converted uint value
Console.Write(" {0}, ", val);
}
}
Output:
Converted uint value from a specified string 12345, 12345, 123456789,
Example 2: For
FormatException
csharp
// C# program to demonstrate the
// Convert.ToUInt32() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of CultureInfo
CultureInfo cultures = new CultureInfo("en-US");
// declaring and initializing String array
string[] values = {"12345", "+12345",
"123456789"};
// calling get() Method
Console.Write("Converted uint value"
+ " of specified strings: ");
for (int j = 0; j < values.Length; j++)
{
get(values[j], cultures);
}
Console.WriteLine("\n");
string s = "123 456, 789";
Console.WriteLine("format of s is invalid ");
// converting string to specified uint
uint val = Convert.ToUInt32(s, cultures);
// display the converted uint value
Console.Write(" {0}, ", val);
}
catch (FormatException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
// Defining get() method
public static void get(string s,
CultureInfo cultures)
{
// converting string to
// specified uint value
uint val = Convert.ToUInt32(s, cultures);
// display the converted
// uint value
Console.Write(" {0}, ", val);
}
}
Output:
Converted uint value of specified strings: 12345, 12345, 123456789,
format of s is invalid
Exception Thrown: System.FormatException
Example 3: For
OverflowException
csharp
// C# program to demonstrate the
// Convert.ToUInt32() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of CultureInfo
CultureInfo cultures = new CultureInfo("en-US");
// declaring and initializing String array
string[] values = {"12345", "+12345",
"123456789"};
// calling get() Method
Console.Write("Converted uint value "
+ "of specified strings: ");
for (int j = 0; j < values.Length; j++)
{
get(values[j], cultures);
}
Console.WriteLine("\n");
string s = "-7922816251426433759354395033500000";
Console.WriteLine("s is less than the MinValue");
// converting string to specified uint
uint val = Convert.ToUInt32(s, cultures);
// display the converted uint value
Console.Write(" {0}, ", val);
}
catch (FormatException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
// Defining get() method
public static void get(string s,
CultureInfo cultures)
{
// converting string to
// specified uint value
uint val = Convert.ToUInt32(s, cultures);
// display the converted uint value
Console.Write(" {0}, ", val);
}
}
Output:
Converted uint value of specified strings: 12345, 12345, 123456789,
s is less than the MinValue
Exception Thrown: System.OverflowException
