Syntax

public static class StringExtensions

Methods

IsHexColor(string)

Determines whether this value is convertible to a hexadecimal color.

Declaration

public static bool IsHexColor(this string hexValue)

Parameters

Type	Name	Description
string	hexValue	The hexadecimal value.

Returns

Type	Description
bool	true if the given string could be converted to a hex color; false otherwise.

IsStringHex(string)

Determines whether the given string is a valid hexadecimal value

Declaration

public static bool IsStringHex(this string hexString)

Parameters

Type	Name	Description
string	hexString	A string that potentially contains a hex value.

Returns

Type	Description
bool	true if the given string could be converted to a hex number; false otherwise.

Replace(string, string, string, int)

Replaces the oldValue with the newValue starting at selectionStart.

Declaration

public static string Replace(this string str, string oldValue, string newValue, int selectionStart)

Parameters

Type	Name	Description
string	str	The string.
string	oldValue	The old value.
string	newValue	The new value.
int	selectionStart	Start of the selection.

Returns

Type	Description
string	Returns a new string in which the oldValue was replaced by the newValue.

Search(string, string)

Returns a value indicating whether the specified String object occurs within this string using a wildcard search and the current culture for lexical comparison.

Declaration

[Pure]
public static bool Search(this string str, string value)

Parameters

Type	Name	Description
string	str	The string.
string	value	The value to search. This may contain wildcards, see examples

Returns

Type	Description
bool	true if str starts with value or the wildcard pattern in value can be found in str, false otherwise.

Remarks

This method performs a case sensitive lexical search according to the CurrentCulture. The search begins at the first character position of this string and continues through the last character position. If value contains a wildcard pattern, the pattern is searched in str, see examples. Otherwise this method only returns true if the string starts with the value.

Valid wildcard patterns are ? to match zero or exactly one character and * to match zero or more characters.

Search(string, string, StringComparison)

Returns a value indicating whether the specified String object occurs within this string using a wildcard search using the specified StringComparison.

Declaration

[Pure]
public static bool Search(this string str, string value, StringComparison comparison)

Parameters

Type	Name	Description
string	str	The string.
string	value	The value to search.
StringComparison	comparison	The StringComparison used for comparing. See remarks for further information.

Returns

Type	Description
bool	true if str starts with value or the wildcard pattern in value can be found in str, false otherwise.

Remarks

This method performs a comparison according to the provided comparison. The search begins at the first character position of this string and continues through the last character position. If value contains a wildcard pattern, the pattern is searched in str, see examples. Otherwise this method only returns true if the string starts with the value.

Valid wildcard patterns are ? to match zero or exactly one character and * to match zero or more characters.

When using Ordinal or OrdinalIgnoreCase the search does not use wildcard patterns.
