C# 排序的动态列表是否为只读?
我有一个动态列表,我尝试对其进行排序,然后根据新的排序顺序更改id:C# 排序的动态列表是否为只读?,c#,asp.net,linq,C#,Asp.net,Linq,我有一个动态列表,我尝试对其进行排序,然后根据新的排序顺序更改id: foreach (Case c in cases) { bool edit = true; if (c.IsLocked.HasValue) edit = !c.IsLocked.Value; eventList.Add(new { id = row.ToString(), realid = "c" + c.CaseID.ToString(),
foreach (Case c in cases)
{
bool edit = true;
if (c.IsLocked.HasValue)
edit = !c.IsLocked.Value;
eventList.Add(new {
id = row.ToString(),
realid = "c" + c.CaseID.ToString(),
title = c.CaseTitle + "-" + c.Customer.CustomerDescription,
start = ResolveStartDate(StartDate(c.Schedule.DateFrom.Value.AddSeconds(row))),
end = ResolveEndDate(StartDate(c.Schedule.DateFrom.Value), c.Schedule.Hours.Value),
description = c.CaseDescription,
allDay = false,
resource = c.Schedule.EmployeID.ToString(),
editable = edit,
color = ColorConversion.HexConverter(System.Drawing.Color.FromArgb(c.Color.Value))
});
row++;
}
var sortedList = eventList.OrderBy(p => p.title);
for (int i = 0; i < sortedList.Count(); ++i)
{
sortedList.ElementAt(i).id = i.ToString();
}
foreach(案例中的案例c)
{
bool edit=true;
如果(c.IsLocked.HasValue)
编辑=!c.IsLocked.Value;
事件列表。添加(新){
id=行。ToString(),
realid=“c”+c.CaseID.ToString(),
title=c.casettitle+“-”+c.Customer.CustomerDescription,
start=ResolveStartDate(StartDate(c.Schedule.DateFrom.Value.AddSeconds(行)),
end=ResolveEndDate(StartDate(c.Schedule.DateFrom.Value)、c.Schedule.Hours.Value),
描述=c.案例描述,
全天=假,
resource=c.Schedule.EmployeID.ToString(),
可编辑=编辑,
color=ColorConversion.HexConverter(System.Drawing.color.FromArgb(c.color.Value))
});
行++;
}
var sortedList=eventList.OrderBy(p=>p.title);
对于(int i=0;i
但是它在sortedList.ElementAt(i.id=i.ToString()上崩溃代码>声明它是只读的
无法将属性或索引器f\uu AnonymousType4.id
分配给--它是只读的
如何更改ID
谢谢如上所述,您无法更新匿名类型,但是您可以修改流程,使用一个查询,首先对项目进行排序,并将项目索引作为参数包含在选择中:
var query = cases.OrderBy(c => c.CaseTitle + "-" + c.Customer.CustomerDescription)
.Select( (c, i) =>
new {
id = i.ToString(),
realid = "c" + c.CaseID.ToString(),
title = c.CaseTitle + "-" + c.Customer.CustomerDescription,
start = ResolveStartDate(StartDate(c.Schedule.DateFrom.Value.AddSeconds(i))),
end = ResolveEndDate(StartDate(c.Schedule.DateFrom.Value), c.Schedule.Hours.Value),
description = c.CaseDescription,
allDay = false,
resource = c.Schedule.EmployeID.ToString(),
editable = c.IsLocked.HasValue ? !c.IsLocked.Value : true ,
color = ColorConversion.HexConverter(System.Drawing.Color.FromArgb(c.Color.Value))
}
);
您可以尝试将排序后的列表复制到新的列表实例什么类型是.id
?如果这是一个只有get访问器的属性,您不能设置它。+1您发布了我刚刚准备发布的确切解决方案。当我看到一个新的答案被贴出来时,我已经把它写好了
