在for循环中我做了：

string[] xFrames = new string[wocl.Count];
            string[] yFrames = new string[wocl.Count];
            List<float> Xframes = new List<float>(wocl.Count);
            List<float> Yframes = new List<float>(wocl.Count);
            for (int i = 0; i < wocl.Count; i++)
            {
                string X = xFrames[i] = string.Format("Frame_X_{0} ", i + 1);
                string Y = yFrames[i] = string.Format("Frame_Y_{0} ", i + 1);

                for (int j = 0; j < wocl[i].Point_X.Count; j++)
                {
                   // xFrames[i] += string.Format("{0},", wocl[i].Point_X[j]);
                   // yFrames[i] += string.Format("{0},", wocl[i].Point_Y[j]);
                    Xframes.Add(wocl[i].Point_X[j]);
                    Yframes.Add(wocl[i].Point_X[j]);

                }

                //xFrames[i].Trim(",".ToCharArray());
                //yFrames[i].Trim(",".ToCharArray());

                setting_file.SetListFloatKey(X, Xframes);
                setting_file.SetListFloatKey(Y, Yframes);

            }

文本文件中的结果是：

Frame_X_1 =325,332,322,332,325
Frame_Y_1 =325,332,322,332,325
Frame_X_2 =325,332,322,332,325,318,332,322,332,325
Frame_Y_2 =325,332,322,332,325,318,332,322,332,325
Frame_X_3 =325,332,322,332,325,318,332,322,332,325,318,332,322,355,325
Frame_Y_3 =325,332,322,332,325,318,332,322,332,325,318,332,322,355,325
Frame_X_4 =325,332,322,332,325,318,332,322,332,325,318,332,322,355,325,318,388,322,355,325
Frame_Y_4 =325,332,322,332,325,318,332,322,332,325,318,332,322,355,325,318,388,322,355,325

不知道为什么 = 之后右边的数字应该在每帧 x 和 y 相同的数字/坐标中。

像在 Frame_X_1 而不是在 Frame_X_4 或不像在 Frame_X_2 出于某种原因，它不断添加数字。

您以这种方式使用双循环：

string[] xFrames = new string[wocl.Count];
string[] yFrames = new string[wocl.Count];

for (int i = 0; i < wocl.Count; i++)
{
   xFrames[i] = string.Format("Frame_X_{0} ", i + 1);
   yFrames[i] = string.Format("Frame_Y_{0} ", i + 1);

   for(int j =0; j < wocl[i].Length; j++)
   {
       xFrames[i] += string.Format("{0},", wocl[i].Point_X[j]);
       yFrames[i] += string.Format("{0},", wocl[i].Point_Y[j]);
   }

   xFrames[i].Trim(",".ToCharArray());
   yFrames[i].Trim(",".ToCharArray());
}

很难说出你想要做什么。但据我所知，您希望通过应用某种转换或组合来生成结果列表，将两个或更多列表组合成其他列表。

为此，我认为您可能需要查看Enumerable.ZipEnumerable.Zip<TFirst, TSecond, TResult>扩展方法。

例如，如果您有两个列表（伪代码）：

val = 1, 2, 3, 4
names = "one", "two", "three", "four"

Zip 算法将允许您将这些组合成一个 int、string 元组的列表：

result = (1,"one"), (2,"two"), (3,"three"), (4,"four")

希望我在这里适合您尝试做的事情。

您似乎想要迭代迭代。 

var output = new StringBuilder();
for(var index=0; index < wocl.Count; index++)
{
  var item = wocl[index];
  output.AppendFormat("Frame_X_{0}", index);

  for(var index2=0; index2 < item.Point_X.Count; index2++ )
  {
     output.AppendFormat(" {0}", item.Point_X[index2]);
  }

  output.AppendFormat("Frame_Y_{0}", index);

  for(var index2=0; index2 < item.Point_Y.Count; index2++ )
  {
     output.AppendFormat(" {0}", item.Point_Y[index2]);
  }
}

string resultText = output.ToString();
