将对象转换为字符串

Question

I use this code for calling a matlab function in C#

Object b;
matlab.Feval("fun444",(int)1,out b,(double)(10));
label1.Text = b.ToString();`

it works and I could saw my answer in b using debugging mode . I want to display his number but it returns to me : system.object[] How can I display the double I saw in the debugger?

Answer 1

You have an array instead of a single object.

You'll need to do something like this... Edit: I didn't see you were setting a textbox the first time I looked at your code.

label1.Text = b[0].ToString();

Answer 2

matlab.Feval为您提供了一个元素的数组，您可以这样得到它：

label1.Text = ((object[])b)[0].ToString()
