Visual Studio Find and Replace Regular Expressions to replace c# 'foreach' loops with 'for' loops.
Useful for Unity scripts that want to reduce dynamic allocations.
Container is assumed to be List, so 'Count' is used rather than Length - will need fixing up after replacement if this is wrong.
Replacements follow this pattern:

    foreach (Type name in container)
    {

... becomes:

    for (int nameIndex = 0; nameIndex < container.Count; ++nameIndex)
    {
        Type name = container[nameIndex];

Also supports type containing "." and ending in "[]", and container containing ".".

Settings to use in Find and Replace dialogue:

Find what:

(?<whitespace>[^\S\r\n]+)foreach[ \t]*\([ \t]*\b(?<type>_+\w+|[\w-[0-9_]][\w\.]*[ \t]*(\[[ \t]*\])?)[ \t]+\b(?<name>_+\w+|[\w-[0-9_]][\w\.]*)\b[ \t]+in[ \t]+\b(?<container>_+\w+|[\w-[0-9_]][\w\.]*)\b[ \t]*\)[ \t\r\n]*{

Replace with:

${whitespace}for (int ${name}Index = 0; ${name}Index < ${container}.Count; ++${name}Index)\r\n${whitespace}{\r\n${whitespace}    ${type} ${name} = ${container}[${name}Index];

Find options:
[ ] Match case
[ ] Match whole word
