String.EndsWith Method (System) | Microsoft Learn

Source:: String.Comparison.cs

Source:: String.Comparison.cs

Source:: String.Comparison.cs

Source:: String.Comparison.cs

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

public:
 bool EndsWith(System::String ^ value, bool ignoreCase, System::Globalization::CultureInfo ^ culture);

public bool EndsWith(string value, bool ignoreCase, System.Globalization.CultureInfo? culture);

public bool EndsWith(string value, bool ignoreCase, System.Globalization.CultureInfo culture);

member this.EndsWith : string * bool * System.Globalization.CultureInfo -> bool

Public Function EndsWith (value As String, ignoreCase As Boolean, culture As CultureInfo) As Boolean

Parameters

value: String

The string to compare to the substring at the end of this instance.

ignoreCase: Boolean

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

culture: CultureInfo

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

Returns

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

Exceptions Examples

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

// This code example demonstrates the 
// System.String.EndsWith(String, ..., CultureInfo) method.

Remarks

This method compares the value parameter to the substring at the end 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 a reference to this same instance or match the end of this string.

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