WriteIf, WriteLineIf

From C# Online.NET (CSharp-Online.NET)—your free C# and .NET encyclopedia

Debug.WriteIf and Debug.WriteLineIf allow you to only print debug if a certain state occurs.

Note: The following examples are not the same. The difference is that on the Release Build the if statement will still exsit if the latter code example is used.

Debug.WriteLineIf(test == true,"Here");

if (test == true) {
   Debug.WriteLine("Here");      
}

Example

using System;
using System.Windows.Forms;
using System.Diagnostics;
 
namespace debugTesting {
 
  public partial class Form1 : Form {
 
    public Form1() {
      InitializeComponent();
    }
 
    private void debugWrite_Click(object sender, EventArgs e) {
 
      int importantVariable = 4;
 
      for (int i = 0; i < importantVariable; i++) {
        Debug.WriteLineIf((i % 2 == 0),"Even number","Loop");
      }
    }
  }
}
