CS0029: Cannot implicitly convert type 'int' to 'string' [duplicate]

问题

This question already has answers here:

Cannot implicity convert type 'int' to 'string' (3 answers)

Closed 4 years ago.

protected void btnAdd_Click(object sender, EventArgs e)
{
    int a = Convert.ToInt32(ltAvailable.Text);
    int b = Convert.ToInt32(txtInput.Text);
    ltTotal.Text = a + b;

How can i add values in a literal and a textbox? Thanks

回答1:

Here:

ltTotal.Text = (a + b).ToString();

回答2:

protected void btnAdd_Click(object sender, EventArgs e)
{
    int a = Convert.ToInt32(ltAvailable.Text);
    int b = Convert.ToInt32(txtInput.Text);
    ltTotal.Text = (a + b).ToString();

You just need to call .ToString() on your calculation result

This would also work

ltTotal.Text = Convert.ToString(a + b)
