String::StartsWith Method (String, Boolean, CultureInfo)

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

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

bool StartsWith(
	String^ value, 
	bool ignoreCase, 
	CultureInfo^ culture


Type: System::String

The string to compare.

Type: System::Boolean

true to ignore case during the comparison; otherwise, false.

Type: System.Globalization::CultureInfo

Cultural information that determines how this string and value are compared. If culture is nullptr, the current culture is used.

Return Value

Type: System::Boolean
true if the value parameter matches the beginning of this string; otherwise, false.


value is nullptr.

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 (String::Empty), must be a reference to this same instance, or must match the beginning of this instance.

This method performs a comparison using the specified casing and culture.

The following 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.
