C#:输出参数索引[i]对于组件来说太高或太低 [英] C#: Output Parameter Index[i] too high or too low for Component
问题描述
运行以下代码时,出现以下错误消息:
The following error message appears when running the code below:
c#:输出参数索引[1]对于组件来说太高或太低.
c#: Output Parameter Index[1] too high or too low for Component.
IGH_DataAccess
已经在说明获取当前迭代计数" 的帮助中提供了迭代计数.在解决方案中第一次在组件上调用SolveInstance()
函数时,迭代计数器将为零.以后每次通话时,它都会加一.使用DA.SetData(0, m_settings[0]);
时,它确实显示第一行.
The IGH_DataAccess
is already providing an iteration count in the help it says "Gets the current iteration count". The first time the SolveInstance()
function is called on a component during a solution the Iteration counter will be zero. It will be incremented by one for every subsequent call. When using DA.SetData(0, m_settings[0]);
it does show the first line.
错误消息出现在所用程序中,并且在DA.SetData(i, m_settings[i]);
上出现以下异常:
The error message appears in the program used and I get the following exception on DA.SetData(i, m_settings[i]);
:
System.Exception occurred

以下是IGH_DataAccess.SetData方法的描述:Stores data in an output parameter during GH_Component.SolveInstance(). Use this function only for setting individual data items. If you want to set lists of data, you *must* call SetDataList() instead.
Herafter is the description of the IGH_DataAccess.SetData Method: Stores data in an output parameter during GH_Component.SolveInstance(). Use this function only for setting individual data items. If you want to set lists of data, you *must* call SetDataList() instead.
将代码更改为DA.SetDataList(i, m_settings[i]);
时,第一行的字符会被拆分,而我希望每一行都将被拆分.
When changing the code to DA.SetDataList(i, m_settings[i]);
the characters of the first line get split while I want every line to get split.
我在做什么错了?
string[] m_settings;
public void ShowSettingsGui()
{
var dialog = new OpenFileDialog {
Filter = "Data Sources (*.ini)|*.ini*|All Files|*.*" };
if (dialog.ShowDialog() != DialogResult.OK) return;
m_settings = File.ReadAllLines(dialog.FileName);
ExpireSolution(true);
}
protected override void SolveInstance(IGH_DataAccess DA)
{
if (m_settings == null)
{
AddRuntimeMessage(GH_RuntimeMessageLevel.Warning,
"You must declare some valid settings");
return;
}
for (var i = 0; i < m_settings.Length; i++)
{
DA.SetData(i, m_settings[i]);
}
}
提前谢谢!
推荐答案
此问题通过使用以下代码解决,将SetData替换为SetDatalist,且不使用循环,也使用其他拆分字符串的方法:
This was solved by using the following code, replacing the SetData by SetDatalist with no loop and a different way of splitting the strings:
string m_settings_temp;
string[] m_settings;
public void ShowSettingsGui()
{
var dialog = new OpenFileDialog { Filter = "Data Sources (*.ini)|*.ini*|All Files|*.*" };
if (dialog.ShowDialog() != DialogResult.OK) return;
m_settings_temp = File.ReadAllText(dialog.FileName);
m_settings = m_settings_temp.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
ExpireSolution(true);
}
protected override void SolveInstance(IGH_DataAccess DA)
{
if (m_settings == null)
{
AddRuntimeMessage(GH_RuntimeMessageLevel.Warning, "You must declare some valid settings");
return;
}
else
{
DA.SetDataList(0, m_settings);
}
}
