重命名Visual Studio上的某些内容（并非全部代码）

考虑这样的代码

    low = a.finder((dashtryBb + dashbtcA), (dashbtcA + dashbtcAa), btctryAa);

    if (low > btclow)
    {
    if (low > btclimit)
    {
    var a = buy.Order("DASHBTC", Math.Round(btclimit / dashbtcA, 8, MidpointRounding.ToZero), dashbtcA);
    var b = buy.Order("DASHTRY", Math.Round(btclimit / dashbtcA, 8, MidpointRounding.ToZero), btctryA);
    var c = buy.Order("BTCTRY", Math.Round(Math.Round(btclimit / dashbtcA, 8, MidpointRounding.ToZero) * dashbtcA, 8, MidpointRounding.ToZero), dashtryB);                             
    }

我想将所有小的“破折号”更改为不同的单词，例如“ eos”，但在特殊区域，并非所有代码。例

low = a.finder((eostryBb + eosbtcA), (eosbtcA + eosbtcAa), btctryAa);

    if (low > btclow)
    {
    if (low > btclimit)
    {
    var a = buy.Order("DASHBTC", Math.Round(btclimit / eosbtcA, 8, MidpointRounding.ToZero), eosbtcA);
    var b = buy.Order("DASHTRY", Math.Round(btclimit / eosbtcA, 8, MidpointRounding.ToZero), btctryA);
    var c = buy.Order("BTCTRY", Math.Round(Math.Round(btclimit / eosbtcA, 8, MidpointRounding.ToZero) * eosbtcA, 8, MidpointRounding.ToZero), eostryB);                             
    }

我尝试过右键单击重命名，但是它不仅在功能上更改了每个“破折号”。任何帮助赞赏。
