Visual Studio 2017 - 如何从ENVDTE获取当前正在运行的版本(Visual Studio 2017 - How to get the current running edition from ENVDTE)

 不知道你是否有一些限制，但这就是我的做法。 
 
 遍历所有对象并将它们放入一个对象中。 该对象的关键将是名称。 检查对象是否存在，如果没有添加它并用[number]替换[number] ，如果对象已经存在，只需添加数字即可。 
 
 一旦你遍历所有的对象，将该对象转换为列表，就是这样。 
 
function groupByName(accum, obj) {
  if (accum[obj.name]) {
    // add all numbers! don't check for uniqueness yet
    accum[obj.name].number = accum[obj.name].concat(obj.number)
  } else {
    accum[obj.name] = obj
    obj.number = [obj.number]
  }
  return accum
}

function removeDuplicates(accum, value) {
  if (accum.length == 0 && accum[accum.length - 1] != value) {
    accum.push(value)
  }
  return accum
}

function toList(context) {
  return function (key) {
    var obj = context[key]
    obj.number.sort()
    obj.number = obj.number.reduce(removeDuplicates, [])
    return obj
  }
}

objs = arrT.reduce(groupByName, {})
output = Object.keys(objs).map(toList(objs))
 
 请注意，我正在编辑第一个对象，所以如果这些对象在其他地方没有用处，那就好了......如果不是，您应该复制reduce函数而不是修改现有对象。 

Not sure if you have some constraints but that's how I'd do it.
 
Loop over all of your object and put them into an object. The key of the object will be the name. Check if the object exists, if it doesn't add it and replace the number by [number], if the object already exists, simply add the number with push.
 
Once you looped over all your objects, convert that object to a list and that's it.
 
function groupByName(accum, obj) {
  if (accum[obj.name]) {
    // add all numbers! don't check for uniqueness yet
    accum[obj.name].number = accum[obj.name].concat(obj.number)
  } else {
    accum[obj.name] = obj
    obj.number = [obj.number]
  }
  return accum
}

function removeDuplicates(accum, value) {
  if (accum.length == 0 && accum[accum.length - 1] != value) {
    accum.push(value)
  }
  return accum
}

function toList(context) {
  return function (key) {
    var obj = context[key]
    obj.number.sort()
    obj.number = obj.number.reduce(removeDuplicates, [])
    return obj
  }
}

objs = arrT.reduce(groupByName, {})
output = Object.keys(objs).map(toList(objs))
 
Note that I'm ediding the first object so if there is no use for those objects anywhere else, that's fine... if not, you should copy in the reduce function instead of modifying and existing object.
