Managed type to unmanaged type

Question

There is a textBox1. Code:

this->textBox1->Location = System::Drawing::Point(233, 20); this->textBox1->Name = L"textBox1"; this->textBox1->Size = System::Drawing::Size(100, 20); this->textBox1->TabIndex = 4; this->textBox1->TextChanged += gcnew System::EventHandler(this, &Form1::textBox1_TextChanged);

And there is a button (that's where the type is when it is pressed). Code:

 private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { // тут например арифметические действия с числом textBox1->TextChanged }

How to read the value of textBox1->TextChanged and in the button convert the type of this value into an int?

@Anatoly Kozlov, To format the code, select it with the mouse and click on the button 101010 of the editor.

textBox1->TextChanged is an event whose processing, judging by your code, is delegated to the textBox1_TextChanged method. Most likely, you are interested in the value of the textBox1->Text property, which is of type string . And in order to get an integer from a string, you need to use one of the overloaded static Parse methods of type System::Int32 .
