C# Invalid expression term ' ='-CodePudding

for (int i = 0; i <= dataGridView1.Rows.Count; i  )
{
    string point_value  = dataGridView1.Rows[i].Cells[1].Value   "|"; 
}

Does anyone know why I am getting this error

Invalid expression term ' ='

for this code?

CodePudding user response：

you create new variable with in your for loop that the reason

if you need to store data each loop you should create variable outside loop

like this

string point_value;
for(int i=0; i <= dataGridView1.Rows.Count; i  )
    {
        point_value  = dataGridView1.Rows[i].Cells[1].Value   "|"; 
    }
