How do I solve error codes E0144 and C2440?

Question

I'm using Visual C++ 2017 with CLR to make a windows program.

Here is the code with the errors:

            String^ in1;
    System::Windows::Forms::TextBox^ textBox1 = in1;
    String^ in2;
    System::Windows::Forms::TextBox^ textBox2 = in2;
    String^ in3;
    System::Windows::Forms::TextBox^ textBox3 = in3;
    String^ in4;
    System::Windows::Forms::TextBox^ textBox4 = in4;
    String^ in5;
    System::Windows::Forms::TextBox^ textBox5 = in5;

Here is what the errors look like in the compiler:

Error (active) E0144 a value of type "System::String ^" cannot be used to initialize an entity of type "System::Windows::Forms::TextBox ^" QMB

Error C2440 'initializing': cannot convert from 'System::String ^' to 'System::Windows::Forms::TextBox ^' QMB

TextBox is a control and cannot match String^. I suggest that you could try the following code.
String^ in1;
System::Windows::Forms::TextBox^ textBox1;
textBox1->Text = in1;
