Else if statement

[JoshLove-msft]

Is there any support for writing an if else statement like this (inlining the second if statement so that it is an else if)

if (condition) 
{
...
}
else if (condition)
{
...
}

I couldn't figure out how to do this using an IfElseStatement. Can this be supported?

Yes we already support this. The IfElseStatement is designed as self-recursive. Here is a real life example:

autorest.csharp/src/AutoRest.CSharp/Common/Output/Models/Types/HelperTypeProviders/TypeFormattersProvider.cs

Line 176 in a695486

new IfElseStatement(new IfStatement(Equal(ch, Literal('+')))

You could write this in this way:

var statement = new IfElseStatement(
	new IfStatement(condition1)
	{
		// statements for your if
	},
	// this is the else statement
	new IfStatement(condition2)
	{
		// statements for your first else if
	}));

This will write into:

if (condition1)
{
	// statements for your if
}
else if (condition2)
{
	// statements for your first else if
}

If you want more else if, you could just use another IfElseStatement as the Else part:

var statement = new IfElseStatement(
	new IfStatement(condition1)
	{
		// statements for your if
	},
	// this is the else statement
	new IfElseStatement(
		new IfStatement(condition2)
		{
			// statements for your first else if
		},
		new IfElseStatement(
			new IfStatement(condition3)
			{
				// statements for your second else if
			},
			new MethodBodyStatement[] {
				// statements for your else
			})));

this will write:

if (condition1)
{
	// statements for your if
}
else if (condition2)
{
	// statements for your first else if
}
else if (condition3)
{
	// statements for your second else if
}
else
{
	// statements for your else
}

I must be doing something wrong - https://github.com/Azure/autorest.csharp/pull/4649/files#diff-e951b5dd9fe84a348c5597b47c30f38972a39dce8d6659979415eafff9ac77daR292

results in https://github.com/Azure/autorest.csharp/pull/4649/files#diff-b5885dc51aea9777fab38b62bda018e5b0fd20dd6fb9f887fd3878639c61c6c9R490-R524

I must be doing something wrong - #4649 (files)

results in #4649 (files)

yes from the generated code, we are having:

if (...)
{
	// ...
}
else
{
	if (...)
	{
		// ...
	}
}

which just works but it is not ideal, somewhere is wrong.
