GZipStream Constructor (Stream^, CompressionLevel)

.NET Framework (current version)
 

Initializes a new instance of the GZipStream class by using the specified stream and compression level.

Namespace:   System.IO.Compression
Assembly:  System (in System.dll)

public:
GZipStream(
	Stream^ stream,
	CompressionLevel compressionLevel
)

Parameters

stream
Type: System.IO::Stream^

The stream to write the compressed data to.

compressionLevel
Type: System.IO.Compression::CompressionLevel

One of the enumeration values that indicates whether to emphasize speed or compression efficiency when compressing the stream.

Exception Condition
ArgumentNullException

stream is null.

ArgumentException

The stream does not support write operations such as compression. (The CanWrite property on the stream object is false.)

You use this constructor when you want to specify whether compression efficiency or speed is more important for an instance of the GZipStream class.

This constructor overload uses the compression mode Compress. To set the compression mode to another value, use the GZipStream(Stream^, CompressionMode) or GZipStream(Stream^, CompressionMode, Boolean) overload.

The following example shows how to set the compression level when creating a GZipStream object.
