【案例】在python中访问自定义c#组件的各种方法
如果需要了解实践的可查询 IronPython
【准备工作】
服务器bin目录下自定义组件，以及相关的代码
```csharp
namespace DynamicFormPlugIn.Tools
{
internal class ToolsTwoArgImpl
{
/*
* 双参数构造函数， 反射访问
*/
string arg1;
string arg2;
public ToolsTwoArgImpl(string a, string b)
{
arg1 = a;
arg2 = b;
}
private string GetMessage()
{
return string.Format("ToolsTwoArgImpl.GetMessage(): arg1 = {0}, arg2={1}", arg1, arg2);
}
}
}
```
【python案例】
```python
import clr
clr.AddReference("mscorlib")
clr.AddReference("System.Data")
#类型容器
clr.AddReference("Kingdee.BOS.DataEntity")
from System import *
from System.Collections.Generic import *
from System.Data import *
##反射命名空间 和类型容器
from System.Reflection import *
from Kingdee.BOS import *
def BarItemClick(e):
if (e.BarItemKey.Equals("tbTestPython", StringComparison.OrdinalIgnoreCase)):
msg =ToolsTwoArgImplTest();
this.View.ShowMessage(msg);
def ToolsTwoArgImplTest():
##私有两参数实例类调用
ans = '';
implType = TypesContainer.GetOrRegister("DynamicFormPlugIn.Tools.ToolsTwoArgImpl,DynamicFormPlugIn");
array = Array.CreateInstance(object, 2);
array[0] = 'my lhs';
array[1] = 'your rhs';
implObj = Activator.CreateInstance(implType, array);
flags = BindingFlags.Instance | BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic;
method = implObj.GetType().GetMethod("GetMessage",flags);
paramArray = Array.CreateInstance(object, 0);
ans += method.Invoke(implObj, paramArray);
ans += '\r\n';
method = implObj.GetType().GetMethod("GetMessageOne",flags);
paramArray = Array.CreateInstance(object, 1);
paramArray[0] = 'input arg';
ans += method.Invoke(implObj, paramArray);
return ans;
```
