索引超出范围。必须是非负数且小于集合的大小。 参数名：指数需要帮助找到索引超出范围的异常消息的原因
我有类WireObjectAnimation：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Windows.Forms;
using DannyGeneral;
namespace AnimationEditor
{
class WireObjectAnimation
{
private List<WireObjectCoordinates> wocl = new List<WireObjectCoordinates>();
private WireObject wo1 = null;
string name;
int ndx;
public WireObjectAnimation(string name,WireObject wo)
{
this.name = name;
wo1 = wo;
WireObjectCoordinates woc;
woc = new WireObjectCoordinates(wo.woc);
wocl.Add(woc);
ndx = 0;
}
public void Save(string path , string fileName , PictureBox pb)
{
int framesNumberX = 0;
int framesNumberY = 0;
string fn;
string t = Path.GetFileNameWithoutExtension(this.name);
if (File.Exists(path + "\\" + "DATABASE" + "\\" + fileName + "\\" + t + ".txt"))
{
try
{
string f = Path.Combine(path + "\\" + "DATABASE" + "\\" + t + "\\" + fileName);
File.Delete(f);
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not delete file from disk. Original error: " + ex.Message);
}
fn = path + "\\" + "DATABASE" + "\\" + t + "\\" + fileName;
}
else
{
fn = path + "\\" + "DATABASE" + "\\" + fileName + "\\" + this.name + ".txt";
}
OptionsFile setting_file = new OptionsFile(fn);
setting_file.SetKey("File Name", fn);
setting_file.SetKey("Object Name", fileName);
setting_file.SetKey("Animation Name", this.name);
setting_file.SetKey("picturebox.Width", pb.Width.ToString());
setting_file.SetKey("picturebox.Height", pb.Height.ToString());
string[] xFrames = new string[wocl.Count];
string[] yFrames = new string[wocl.Count];
string X="";
string Y="";
for (int i = 0; i < wocl.Count; i++)
{
X = string.Format("Frame_X_{0} ", i + 1);
Y = string.Format("Frame_Y_{0} ", i + 1);
framesNumberX ++;
framesNumberY ++;
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]);
}
string tt = xFrames[i].Trim(",".ToCharArray());
string yy = yFrames[i].Trim(",".ToCharArray());
setting_file.SetKey(X, tt);
setting_file.SetKey(Y, yy);
}
int resultX = framesNumberX/2;
int resultY = framesNumberY/2;
setting_file.SetKey("Number Of Frames X", resultX.ToString());
setting_file.SetKey("Number Of Frames Y", resultY.ToString());
}
public void Load(string path,string fileName)
{
int numberofframesX = 0;
int numberofframesY = 0;
string framesX = "";
string framesY = "";
string X = "";
string Y = "";
string t = path + "\\" + fileName;
OptionsFile setting_file = new OptionsFile(t);
string XX = setting_file.GetKey("Number Of Frames X");
string YY = setting_file.GetKey("Number Of Frames Y");
numberofframesX = Convert.ToInt32(XX);
numberofframesY = Convert.ToInt32(YY);
for (int i = 1; i < numberofframesX ; i++)
{
X = string.Format("Frame_X_{0} ", i);
framesX = setting_file.GetKey(X);
List<string> floatStrings = new List<string>(framesX.Split(new char[] { ',' }));
List<float> test = floatStrings.Select(tempStr => (float)Convert.ToDouble(tempStr)).ToList();
wo1.woc.Point_X = test;
}
for (int i = 1; i < numberofframesY; i++)
{
Y = string.Format("Frame_Y_{0} ", i);
framesY = setting_file.GetKey(Y);
List<string> floatStrings = new List<string>(framesY.Split(new char[] { ',' }));
List<float> test = floatStrings.Select(tempStr => (float)Convert.ToDouble(tempStr)).ToList();
wo1.woc.Point_Y = test;
}
}
public void SetFrame(int frameNumber, WireObjectCoordinates woc)
{
wocl[frameNumber].Set(woc);
}
public WireObjectCoordinates GetFrame(int frameNumber)
{
if (frameNumber > wocl.Count)
{
throw new Exception("not allowed!");
}
if (frameNumber == wocl.Count)
{
WireObjectCoordinates woc;
woc = new WireObjectCoordinates(wocl[wocl.Count - 1]);
wocl.Add(woc);
return woc;
}
else
{
return wocl[frameNumber];
}
}
}
}
现在，当即时通讯做加载负载功能，我看到点它的加载它好。 但后来我试图移动trackBar栏滚动到右侧，然后即时获取异常。现在这个：wo1.woc.Point_X = test; woc有4个索引，每个索引中的Point_X和Point_Y都填充了数字。在跟踪条的Form1的滚动事件中使用的getFrame
在这个类中，我有功能SETFRAME和的getFrame和IM：
private void trackBar1_Scroll(object sender, EventArgs e)
{
currentFrameIndex = trackBar1.Value;
textBox1.Text = "Frame Number : " + trackBar1.Value;
wireObject1.woc.Set(wireObjectAnimation1.GetFrame(currentFrameIndex));
LoadPictureAt(trackBar1.Value, sender);
button1.Enabled = false;
button2.Enabled = false;
button3.Enabled = false;
button4.Enabled = false;
button8.Enabled = false;
SaveFormPicutreBoxToBitMapIncludingDrawings();
return;
}
现在，当IM一旦移动跟踪条向右应该画下一组从Point_X和Point_Y号而不是它的去WireObjectCoordinates类和扔有例外：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace AnimationEditor
{
class WireObjectCoordinates
{
public List<float> Point_X = new List<float>();
public List<float> Point_Y = new List<float>();
public WireObjectCoordinates()
{
}
public WireObjectCoordinates(WireObjectCoordinates w)
{
Point_X.AddRange(w.Point_X);
Point_Y.AddRange(w.Point_Y);
}
public void Set(WireObjectCoordinates w)
{
for (int i = 0; i < Point_X.Count; i++)
{
Point_X[i] = w.Point_X[i];
Point_Y[i] = w.Point_Y[i];
}
}
}
}
唯一的例外是就行：Point_X [I] = w.Point_X [I]; Point_X [i]现在包含从[0]到[3]的4个索引，每个索引包含一个数字，如332.0 333.0 334.0 335.0 而w.Point_X [i]现在只包含一个索引[0]，并且此索引的数目为332.0
我只是不明白为什么例外是在这一行。
这个想法是，当我将trackBar移动到右边时，它应该绘制wo1.woc.Point_Y和wo1.woc.Point_X中的下一个坐标，但我想我在Load函数中做了错误的操作？我不知道为什么它抛出异常，它只有当我将轨道栏向右移动一次。
