C# Method to determine whether multiple text boxes are empty

This article example describes the method of C# to determine whether multiple text boxes are empty. Share it for your reference. The specific implementation method is as follows:

/// &lt;summary&gt;
/// Custom method to determine whether the txt tag in the project is empty/// &lt;/summary&gt;
/// <param name="txt">Tags to be judged as empty</param>/// <returns>Is it all empty? If nothing is empty, return true </returns>bool CheckEmpty(params TextBox[] txt)
{
bool flag = true;
for (int i = 0; i &lt; ; i++)
{
if (txt[i].() == "")
{
("The option marked * cannot be empty, please re-enter!");
txt[i].Focus();
flag = false;
break;
}
}
return flag;
}

I hope this article will be helpful to everyone's C# programming.
