This page lists some commonly required analogues between Java and C# that are not so trivial. This collection has been compiled while porting GitSharp.

Contents 1 Unsigned right shift operator (>>>) 2 string.Substring 3 Octal literals (i.e. 0001) 4 synchronized 5 Streams and Buffers

Unsigned right shift operator (>>>)

Java:

{{{1}}}

C#:

{{{1}}}

string.Substring

Java:

someString.substring(int, int)

An extension method that resembles the Java version is available in GitSharp.Util:

C#:

someString.Slice(int, int)

Octal literals (i.e. 0001)

C# does not support octal literals (starting with a leading zero in java) and interprets them wrongly as decimal. You need to replace them by the corresponding decimal or hex literals.

Java:

{{{1}}}

C#

{{{1}}}

synchronized

Java:

synchronized void a_method() { ...

}

C#

[MethodImpl(MethodImplOptions.Synchronized)] public void a_method() { ...

}

When inlined, synchronized(this) is of course equivalent to lock(this)

Streams and Buffers

Java

new ByteArrayOutputStream();

C#

new BinaryWriter(new MemoryStream());
