Write(Char[], Int32, Int32)

Source:

StringWriter.cs

Writes a subarray of characters to the string.

public:
 override void Write(cli::array <char> ^ buffer, int index, int count);

public override void Write (char[] buffer, int index, int count);

override this.Write : char[] * int * int -> unit

Public Overrides Sub Write (buffer As Char(), index As Integer, count As Integer)

Parameters

buffer

Char[]

The character array to write data from.

index

Int32

The position in the buffer at which to start reading data.

count

Int32

The maximum number of characters to write.

Exceptions

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

index or count is negative.

ArgumentException

(index + count)> buffer. Length.

ObjectDisposedException

The writer is closed.

Examples

This code example is part of a larger example provided for the StringWriter() constructor.

// Use the three overloads of the Write method that are 
// overridden by the StringWriter class.
strWriter->Write( "file path characters are: " );
strWriter->Write( Path::InvalidPathChars, 0, Path::InvalidPathChars->Length );
strWriter->Write( Char::Parse( "." ) );

// Use the three overloads of the Write method that are
// overridden by the StringWriter class.
strWriter.Write("file path characters are: ");
strWriter.Write(
    Path.InvalidPathChars, 0, Path.InvalidPathChars.Length);
strWriter.Write('.');

' Use the three overloads of the Write method that are 
' overridden by the StringWriter class.
strWriter.Write("file path characters are: ")
strWriter.Write( _
    Path.InvalidPathChars, 0, Path.InvalidPathChars.Length)
strWriter.Write("."C)

Remarks

This method overrides TextWriter.Write.

This method writes count characters of data to this StringWriter from buffer, starting at position index.

public override void Write (string? value);

override this.Write : string -> unit

Public Overrides Sub Write (value As String)

Parameters

value

String

The string to write.

convertedCharacter = Convert::ToChar( intCharacter );
if ( convertedCharacter == '.' )
{
   strWriter->Write(  ".\n\n" );
   
   // Bypass the spaces between sentences.
   strReader->Read();
   strReader->Read();
}

convertedCharacter = (char)intCharacter;
if(convertedCharacter == '.')
{
    strWriter.Write(".\n\n");

    // Bypass the spaces between sentences.
    strReader.Read();
    strReader.Read();
}

convertedCharacter = Convert.ToChar(intCharacter)
If convertedCharacter = "."C Then
    strWriter.Write("." & vbCrLf & vbCrLf)
