    Splitting text

    I'm trying to split a text from a text file into token strings but I really have no clue

    Code:
    if ( (openFileDialog1->OpenFile()) != nullptr ){
         this->filename = openFileDialog1->SafeFileName;
         this->reader = gcnew System::IO::StreamReader(filename);
         this->textBox1->Text="";
         std::string * input_array;
         do
    	{
                	this->input= reader->ReadLine();
    		String^ delimeter = ",";
    		foreach(delimeter in input)
    			{
    				input_array = input->Split(delimeter);
    			}
    		}  
         while(reader->Peek() != -1);
    }     
     this->reader->Close();this->reader=nullptr;
    Here are the errors

    I figured out a solution
    Code:
    if ( (openFileDialog1->OpenFile()) != nullptr ){
    					 this->filename = openFileDialog1->SafeFileName;
    					this->reader = gcnew System::IO::StreamReader(filename);
    					this->textBox1->Text="";
    					System::String^ split;
    					do
    					{
    						this->input= reader->ReadLine();
    						String^ delimeter = ",";
    						int start_index = 0;
    						for (int index = this->input->IndexOf(delimeter, start_index); this->input->LastIndexOf(delimeter); index ++)
    								{
    									split = this->input->Substring(index,this->input->IndexOf(delimeter));
    								}
    					}   
    					while(reader->Peek() != -1);
    				}
    				 this->reader->Close();this->reader=nullptr;
    
    			  }
