class System.Text.EncoderReplacementFallbackBuffer
Assembly: System.Runtime
Inheritance: object → EncoderFallbackBuffer → EncoderReplacementFallbackBuffer
Represents a substitute input string that is used when the original input character cannot be encoded. This class cannot be inherited.
Properties
public
int
Remaining
Gets the number of characters in the replacement fallback buffer that remain to be processed.
Methods
public
bool
Fallback(char charUnknownHigh,
char charUnknownLow,
int index)
charUnknownHigh
The high surrogate of the input pair.
charUnknownLow
The low surrogate of the input pair.
index
The index position of the surrogate pair in the input buffer.
Returns <see langword="true" /> if the replacement string is not empty; <see langword="false" /> if the replacement string is empty.
Indicates whether a replacement string can be used when an input surrogate pair cannot be encoded, or whether the surrogate pair can be ignored. Parameters specify the surrogate pair and the index position of the pair in the input.
public
bool
Fallback(char charUnknown,
int index)
charUnknown
An input character. This parameter is ignored in this operation unless an exception is thrown.
index
The index position of the character in the input buffer. This parameter is ignored in this operation.
Returns <see langword="true" /> if the replacement string is not empty; <see langword="false" /> if the replacement string is empty.
Prepares the replacement fallback buffer to use the current replacement string.
public
char
GetNextChar() Returns The next Unicode character in the replacement fallback buffer that the application can encode.
Retrieves the next character in the replacement fallback buffer.
public
bool
MovePrevious() Returns <see langword="true" /> if the <see cref="M:System.Text.EncoderReplacementFallbackBuffer.MovePrevious" /> operation was successful; otherwise, <see langword="false" /> .
Causes the next call to the <see cref="M:System.Text.EncoderReplacementFallbackBuffer.GetNextChar" /> method to access the character position in the replacement fallback buffer prior to the current character position.
public
void
Reset()
Initializes all internal state information and data in this instance of <see cref="T:System.Text.EncoderReplacementFallbackBuffer" /> .
public
bool
Equals(object obj)
Inherited from object
obj
The object to compare with the current object.
Returns <see langword="true" /> if the specified object is equal to the current object; otherwise, <see langword="false" /> .
Determines whether the specified object is equal to the current object.
protected
void
Finalize()
Inherited from object

public
int
GetHashCode()
Inherited from object
Returns A hash code for the current object.
Serves as the default hash function.
public
Type
GetType()
Inherited from object
Returns The exact runtime type of the current instance.
Gets the <see cref="T:System.Type" /> of the current instance.
protected
object
MemberwiseClone()
Inherited from object
Returns A shallow copy of the current <see cref="T:System.Object" /> .
