以上代码改编成C#，如果三个变量循环+0.000001，嵌套3层for循环会造成假死，请问有什么解决办法或其他思路？

for (F46 = 0.000001; F47 > 1.001 || F47 < 0.999; F46 = F46 + 0.000001)
{
for (F42 = 0.000001; F52 > 1.001 || F52 < 0.999; F42 =F42 + 0.000001)
{
for (F38 = 0.000001; F53 > 1.001 || F53 < 0.999; F38 = F38 + 0.000001)
{

造成假死，是因为主界面被阻塞，你开一个线程跑，就可以了。
