vb.net如何发送含双引号的字符串。转义双引号

中文引号直接放在字符串里面即可，英文引号用Chr(34)表示，如

Dim phrase As String = "a" & Chr(34) & "b"


Dim strparam As String = "inputJson :{"
        strparam += Chr(34) & "fromUser" & Chr(34) & ":" & Chr(34) & "fmps" & Chr(34) & ","
        strparam += Chr(34) & "toUser" & Chr(34) & ":" & Chr(34) & "fcps" & Chr(34) & ","
        strparam += ""
        strparam += ""

输出： inputJson:{"fromUser":"fmps","toUser":"fcps",
