public:
 virtual int ReadBlock(Span<char> buffer);

Public Overridable Function ReadBlock (buffer As Span(Of Char)) As Integer

Parameters

buffer
Span<Char>

Returns

ReadBlock(Char[], Int32, Int32) ReadBlock(Char[], Int32, Int32) ReadBlock(Char[], Int32, Int32) ReadBlock(Char[], Int32, Int32)

Reads a specified maximum number of characters from the current text reader and writes the data to a buffer, beginning at the specified index.

public:
 virtual int ReadBlock(cli::array <char> ^ buffer, int index, int count);
public virtual int ReadBlock (char[] buffer, int index, int count);
abstract member ReadBlock : char[] * int * int -> int
override this.ReadBlock : char[] * int * int -> int
Public Overridable Function ReadBlock (buffer As Char(), index As Integer, count As Integer) As Integer

Parameters

buffer
Char[]

When this method returns, this parameter contains the specified character array with the values between index and (index + count -1) replaced by the characters read from the current source.

index
Int32 Int32 Int32 Int32

The position in buffer at which to begin writing.

count
Int32 Int32 Int32 Int32

The maximum number of characters to read.

Returns

The number of characters that have been read. The number will be less than or equal to count, depending on whether all input characters have been read.

Exceptions

The buffer length minus index is less than count.

Remarks

The position of the underlying text reader is advanced by the number of characters that were read into buffer.

The method blocks until either count characters are read, or all characters have been read. This is a blocking version of Read.
