编辑2 我意外地传达了异常是IndexOutOfBounds类型，但它实际上是IndexOutOfRange类型。
我正在尝试将一些对象保存到服务器。这些是采取的行动：
＃3上的过程错误。出于某种原因，我在循环遍历TextModel列表时得到IndexOutOfRange异常。将所有TextModel列表元素添加（循环）到新的TextInfo列表后，出现错误。这当它试图增加for循环计数器（i）时。我希望它增加i然后在条件不满足时退出循环，但它似乎在i ++上出错。
我不知道是什么导致了这个错误。如代码所示，我只使用列出的对象来填充新对象的属性，我不会尝试在循环中编辑属性。任何可能导致问题的见解都会有所帮助。提前谢谢。

显然这还不够清楚。所有随帖子发送的对象都按预期在控制器中接收。 Count始终保持预期的元素数量，并且所有元素都已正确设置。请参阅JSON示例＆amp;图1有关详细信息。
Javascript（＃1）中定义的文本对象
function Text() {
//this.Id = 0;
this.text = "Hallo";
this.x = 0;
this.y = 0;
this.fillColor = "black";
this.fontFamily = "Arial";
this.fontStyle = "normal";
this.fontSize = "18pt";
this.fontWeight = "normal";
this.textAlignment = "start";
this.angle = 0;
}
function addText(text, fillColor, fontSize, fontFamily, fontStyle, fontWeight, textAlignment, x, y, angle) {
var textTemp = new Text;
textTemp.text = multilineText(text, fontSize, fontFamily, fontStyle);
textTemp.fillColor = fillColor;
textTemp.fontSize = fontSize;
textTemp.fontFamily = fontFamily;
textTemp.fontWeight = fontWeight;
textTemp.fontStyle = fontStyle;
textTemp.x = x;
textTemp.y = y;
textTemp.textAlignment = textAlignment;
textTemp.angle = angle;
textObjects.push(textTemp);
}
Javascript JQuery.Post＆amp;控制器中的TextModel（＃2）
// Saves page information
// Called on Save, Next / Previous Page.
// @param curPageNum The currently selected page's number.
function savePage(curPageNum) {
var pageNumber = curPageNum;
var json = JSON.stringify({ TextObjects: textObjects, ImageSource: imageSource, CurrentPageNumber: pageNumber });
alert(json);
$.ajax({
url: "/NextprintPhotobook/SavePageInfo",
type: "POST",
data: json,
contentType: 'application/json; charset=utf-8',
success: function (data) {
console.log(data.message);
showSuccess(data.message);

error: function (data) {
console.log(data);
showError("Er is een fout opgetreden bij het opslaan van de foto.");
