substring and return the value after a specific character
提问by Fire Hand
"Testing.BSMain, Text: Start Page"
“Testing.BSMain，文本：起始页”
I would like to substring the value above and returning me only the value after the ": "in vb.net. How can i do that?
我想对上面的值进行子字符串化，并只返回vb.net 中“:”之后的值。我怎样才能做到这一点？

Assumes no error checking:
假设没有错误检查：
Dim phrase As String = "Testing.BSMain, Text: Start Page".Split(":")(1)
which simply splits the phrase by the colon and returns the second part.
它只是用冒号分割短语并返回第二部分。
To use SubString, try this:
要使用 SubString，试试这个：
Dim test As String = "Testing.BSMain, Text: Start Page"
Dim phrase As String = test.Substring(test.IndexOf(":"c) + 1)

you can use the split method to return the value after the colon :
您可以使用 split 方法返回冒号后的值：
Dim word as String = "Testing.BSMain, Text: Start Page"
Dim wordArr as String() = word.Split(":")
Dim result as String = wordArr(1);
