String.StartsWith Method (String, Boolean, CultureInfo)

Note: This method is new in the .NET Framework version 2.0.

Determines whether the beginning of this string matches the specified string when compared using the specified culture.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public bool StartsWith (
	string value,
	bool ignoreCase,
	CultureInfo culture
)
public boolean StartsWith (
	String value, 
	boolean ignoreCase, 
	CultureInfo culture
)
public function StartsWith (
	value : String, 
	ignoreCase : boolean, 
	culture : CultureInfo
) : boolean

Parameters

value

The String object to compare.

ignoreCase

true to ignore case when comparing this string and value; otherwise, false.

culture

Cultural information that determines how this string and value are compared. If culture is a null reference (Nothing in Visual Basic), the current culture is used.

Return Value

true if the value parameter matches the beginning of this string; otherwise, false.

Exception typeCondition

ArgumentNullException

value is a null reference (Nothing in Visual Basic).

This method compares the value parameter to the substring at the beginning of this string that is the same length as value, and returns a value that indicates whether they are equal. To be equal, value must be an empty string (Empty), a reference to this same instance, or match the beginning of this instance.

This method performs a word (culture-sensitive) comparison using the specified casing and culture.

The following code example determines whether a string occurs at the beginning of another string. The StartsWith method is called several times using case sensitivity, case insensitivity, and different cultures that influence the results of the search.
