查找和替换c#中的文本

本文关键字:文本 替换 查找 | 更新日期: 2023-09-27 18:04:13

我需要在我的程序中添加功能,以便导入的任何文件都可以在addTestingPageContentText方法的"中找到文本,如下所示。然后将每行上的两个值添加到具有2列的datagridview中,因此第一列中的第一个文本然后第二列中的第二个文本。我怎么去找"sometext"呢?

    addTestingPageContentText("Sometext", "Sometext");
    addTestingPageContentText("Sometext2", "Sometext2");
... continues n number of times.

查找和替换c#中的文本

既不快速也不高效,但对于正则表达式新手来说更容易理解:

while (!endOfFile)
{
    //get the next line of the file
    string line = file.readLine();
    EDIT: //Trim WhiteSpaces at start
    line = line.Trim();
    //check for your string
    if (line.StartsWith("addTestingPageContentText"))
    {
        int start1;
        int start2;
        //get the first something by finding a "
        for (start1 = 0; start1 < line.Length; start1++)
        {
            if (line.Substring(start1, 1) == '"'.ToString())
            {
                start1++;
                break;
            }
        }
        //get the end of the first something
        for (start2 = start1; start2 < line.Length; start2++)
        {
            if (line.Substring(start2, 1) == '"'.ToString())
            {
              start2--;
              break;
            }
        }
        string sometext1 = line.Substring(start1, start2 - start1);
        //get the second something by finding a "
        for (start1 = start2 + 2; start1 < line.Length; start1++)
        {
            if (line.Substring(start1, 1) == '"'.ToString())
            {
                start1++;
                break;
            }
        }
        //get the end of the second something
        for (start2 = start1; start2 < line.Length; start2++)
        {
            if (line.Substring(start2, 1) == '"'.ToString())
            {
                start2--;
                break;
            }
        }
        string sometext2 = line.Substring(start1, start2 - start1);
    }
}

然而,我强烈建议你去网上看一些很棒的教程。这个很好

表达式"'"[^"]*'""将找到每个…
