查找并替换字符串中的特定单词

Question

我想写一些c＃代码，我在字符串中找到一个特定的单词，并从字符串中删除它而不删除整个字符串。

我尝试了这个，但它不起作用：

if (openFile.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    // Read the files
    for (int i = 0; i < openFile.FileNames.Count(); i++ )
    {
        if (openFile.FileNames[i].Contains("Unknown Album"))
        {
            openFile.FileNames[i] = 
                openFile.FileNames[i].Replace("Unknown Album", string.Empty);
        }
    }
}

Answer 1

.FileNames类的OpenFileDialog属性只读。您必须将值存储在临时字符串中。

Answer 2

if (openFile.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    // Read the files
    for (int i = 0; i < openFile.FileNames.Count; i++ )
    {
        var file = openFile.FileNames[i];
        if (file.Contains("Unknown Album") && file  != "Unknown Album")
        {
            openFile.FileNames[i] = file.Replace("Unknown Album", string.Empty);
        }
    }
}
